Sharp MX-2640 Error Code F2-40 | Solution

Sharp MX-2640 Error Code F2-40 | Solution

Actual Scenario:

Customer complains that copies and prints are displaying feint bands across the print direction and then, all of a sudden, the error code L2-40 is displayed and the machine cannot be used. Even if there are no feint banding issues this error code can suddenly appear. What does the service manual say about this error code?

Mx-2640 service manual comments: F2-40 – Toner empty sensor trouble (K) – Black

This suggests that the toner supply is not reaching a specific level of supply after various tests are performed. At first one could locate the relevant shutters and check to ensure there are no blockages either in the toner cartridge, developer assembly or the machine. All appeared fine.

Error F2-40 Cause: In this instance it appeared that the cover for the black drum assembly had been incorrectly fitted so that the mylar sheet was caught under the charge grid wire which caused it to come in direct contact with the OPC drum, causing a short. It’s not easy to notice without a close look since the mylar guide is transparent and may look perfectly fine. Look closely at the pictures below:

My finger is pointing to where the clear plastic mylar attached to the black cover had caught under the edge of the grid wire which pushed it up against the drum causing hell to break loose. The build up of toner you can see better to the right caused the feint banding and you will also notice the excessive toner trapped on the cleaning blade just behind the grid wire in the example to the right.

The excess toner stuck to the grid wire and cleaning blade had also damaged the surface of the drum as a result and you may just be able to see in the picture below:

How to remedy Error F2-40 on the Sharp MX-2640

Well, your drum is probably damaged and your grid wire too. If not and if you do not have the parts there and then you could try cleaning the grid wire and making sure the mylar is not trapped by gently running your finger behind it to make sure it is over and not under the grid wire. In our case, the consequence was that the developer had seriously depleted due to the excessive discharge and the feint bands could be seen directly on the mag roller. I replaced the following parts:

Black Developer – Part Number: 36GVBA
Cleaning Blade and Charger Kit – Part Number: MX-230MK
Drum Unit – Part Number: 36GRSA

Epson Workforce WF-3620 Review

Epson Workforce WF-3620 Owner Review

Yes, you are right. As much as I love Canon, Sharp, Xerox and Kyocera, I went for an Epson as the choice for my home printer. Mainly because of price, but now that I have owned an Epson costing around £100, I am sold on them. It is compact, sturdy and well made. The document feeder works very well and it performs duplexing for documents and prints very well for such a small machine. Setting it up out of the box takes a little while but all of the instructions are included and even if you buy it secondhand you could just Google for the instruction with not much difficulty. The paper cassette is capable of holding 250 sheets which is also very generous for a machine in this price range.

Scanning to the Cloud is a cinch

The Epson WF-3620 is able to qickly scan to various cloud destinations including to Google Drive, Dropbox, Microsoft OneDrive, Evernote and Email. Epson iPrint offers an online and offline control centre for all of your documents and pictures with handy options to move or print them. You can set up regularly used destinations such as Jay’s Google Drive or Usiholo’s Hotmail. The printer is Air Print enabled and I am amazingly impressed with it so far. My youngest son, Osagie, stuck pencils and rubbers down into the paper pick up assembly so I had to spend around 30 minutes fixing it and now it’s as good as new again.

Printer ink easily available but a little pricey

Original Alarm Clock black inks starts from around £25 and the colour pack at around £23. A good point to remember is that your inkjet printer will perform optimally and use the least ink if you don’t switch it off. Allow it to go into standby as it doesn’t use much energy. Everytime you restart an inkjet printer it goes through a cleaning routing which purges the print heads. This uses ink to clear any potential blockages but causes excessive waste if you keep switching the thing off and on. The machine will initiate a cleaning cycle periodically when not in use so using it regularly can get the most prints from your cartridges. Having said that, don’t go around printing everything if you don’t need to as that would be counterproductive.

Epson Workforce WC-3620 Verdict

Fantastic value for money and great build quality. Ink cartridges a little expensive but the machine is of a far superior build quality than, Kodak or HP equivalents. The document feeder can handle at least 20 sheets with easily to access rollers for cleaning purposes. AirPrint enabled out of the box.

Canon Printer Support in East London

Canon Printer Support in East London

East London copier companies are plentiful in and around the Greater London area and even Canon printer support companies outside of London have a presence in Central London and East London. It is far cheaper for a copier company to be located where space is not such a premium due to the need for warehouse space to allow for machine storage, workshops, consumables and spare parts inventory. The benefits of using printer support and copier companies outside of Central London are enormous such as the fact that their pricing may be more keen due to not having the huge overheads associated with being located in the city. On the other hand, copier companies still left in the city (and most other cities) such as Apogee and Danwood can drive down prices by being massive entities with thousands of machines and clients nationally. This affords them the strongest buying power in the country behind the manuafacturers. However, Apogee just took over Danwood a few months ago making Apogee huge. But less of the digression. If you are looking for Canon printer support in east London and you don’t already have a service contract then we can help you to avoid unecessary call out charges.

Common Printer Faults that Can be Solved Easily

There are a number of technical issues that can arise with your printer/copier that can easily be remedied if you know what to look for. They could save you valuable down time at the very least, and hard cash at the very best! For the purposes of making this printer support help article more beneficial to all readers we will try to refrain from direct reference to any particular manuafacturer although this may be a little hard to do at times since the author has his manufacturer biases.

Copier Paper Jams

The first rule to successfully clearing a jam is to actually follow the on screen instructions for clearing jams. It sounds obvious but you would be surprised just how many people just open doors and pull out paper cassettes without reading anything on the screen. Invariably, if you open up a paper cassette without following onscreen prompts, you are likely to tear some trapped paper making it impossible to remove without calling in help. Which means money. As a rule, never slide out a paper cassette on the front of a machine withot opening up all side doors first. Chances are you will expose the jammed sheet sticking out of the side. Thats the piece you could have torn! If you can see that the paper is just a little way up the side of the machine with some still back in the machine then release the cassette very slightly but do not pull out. The trapped paper, if part of it is still stuck in the cassette, will be easier to remove from the side with the cassette released. If your copier is a heavy duty machine with mulitple draws that pull out from the front be similarly cautious. If you do pull out draws from the front then always open up side doors first and try to pull out multiple draws/units together. If you hear a scrunching sound when you move a draw then stop and think again, something is tearing or squashing (getting jammed worse). Most users don’t seem to be bothered to find out much about their copier and end up destroying their machine without even knowing how. Understand how your machine works in terms of paper feed and it could save you time and money. Most photocopiers have at least one printer door which will expose the paper feed; this is the area where the paper has left the cassette and travels up the side of the machine where the latent image will be transferred onto the paper and then the fuser unit will fix the toner image to the paper. The paper path will either feed out of the cassettte to the left, right or to the rear in the case of smaller printers. If the paper feeds up the rear of the machine then access doors will be to the front and the back.

Ghost Jams

A jam or not a jam, that is the question. A common jam condition is known as the ‘ghost jam’ where you just cant find that stupid piece of paper. You open and close covers until you start slamming covers which only potentially creates another problem or set of problems. If you are really sure that you have removed all pieces of paper and you can’t hear any tearing or scrunching sounds in the machine as you open and close doors, then there is a good chance that the problem is in the paper cassette itself. A good tip is to restart the machine since an exact jam location may be displayed after doing this. Otherwise, open the paper cassette to see if there is any paper causing issues in the tray. Most paper cassettes have a metal lifting plate that lifts the stack of paper high enough for the pick up roller to take away the top sheet. If a sheet or several sheets are incorrectly loaded it could prevent the lifting plate from rising. Take the whole stack of paper out and visually check that none of the sheets lower down the stack are not squared correctly. You may find a sheet or sheets folded under which can cause havoc as the lifting plate will get confused when it tries to rise the top sheet into position. The display may keep telling you to open the lower printer door but there is nothing there. This is another sign that the problem is in the cassette. An incorrectly loaded sheet of paper can actually trap the lifting plate so it cannot rise.

Tip: Never add paper if there is already paper. Only add paper when the tray is empty or remove all the existing paper and add to the stack outside of the machine ensuring that all sheets are aligned properly. Also, fan out sheets to ensure no static is present which can cause jams or multifeeding.

Document Multifeeding

A photocopier can not do anything without something to copy. The condition and quality of the original documents to be copied or scanned can make all the difference between them being properly fed through the document feeder and them jamming inside. Always check that your documents are not stapled especially if you have a mixed set. Straighten out any dog ears and try to feed the set of documents in with the straightest edge first. For freshly printed documents you wish to scan to email or copy, be sure to fan the sheets out to remove static. Static can cause the sheets to stick together and feed multiple sheets through. If you have a document jam please open all covers and turn any green knobs to move paper out of the jam position. Don’t just yank documents out of the machine, especially not backwards which can snap sensor actuators and your document feeder will be unusable until you call the copier guy. Most document feeders employ one of two methods to feed documents; a pick up, separation and feed roller configuration or a pick up, feed and separation (or friction) pad. The pick up roller does just that, picks the paper from its sitting position and drags it to meet the feed roller. The separation roller is usually located on the bed of the feed path directly under the feed roller and acts to resist feed by slowing its rotation in relation to the feed roller. This prevents all of the sheets, other than the top document, from feeding through. If the sep roller is dirty or worn it will fail to resist and allow more than one sheet through. If its worn there is nothing you can do unless you have another rollwer and know how to change it but if it is dirty you can easily clean it with WD40 or even glass cleaner. It’s only rubber. If you machine employs a separation pad then you will just see a rubber pad located directly below the feed roller when you lift the document feeder cover/flap. If the pad appear slippery or shiny then this will most likely can multiple feeding issues since more than one sheet slips over it. It is sprung loade so the friction is caused by the paper butting up against a surface which grips it to stop it.

Feint Lines on Print and Copy

Both printing and copying produces the printed image and feint lines are usually caused by something in the print processing area, not the scanner. Of course, print jobs don’t use the document scanner but it is easy for image faults to confuse you into thinking something in the scanner is causing the problem. To isolate the print engine perform a print job or internal print job. If the feint line is on the print then it is not your scanner. Most modern laser machines employ a drum, developer unit, transfer assembly, main charge and cleaning blades. If the feint lines is caused by components not accessible to the user then you will need to call in an engineer but there are trhings you cant try first. Most machines will porivde a way for customers to clean the main charge although many don’t know that they can. Open up the front door and look for any instructions on the inner side of the door. If you see what looks like a plastic wand with a white pad on one end, that is a cleaning tool. This pad is normally found on colour machines and there will be four corresponding apertures where you slide this rod in and push it back and forth a few times. This cleans the laser slip glass for each colour. When laser glass protection strips get dirty it can cause feint lines on copies. There may also be other rods sticking out from the machine in four places to clean the main charge corona (wire) for each colour (Cyan, Magenta, Yellow and Black or CMYK). If it is a black and white machine there would be just one for black. Get to know where the cleaning tools for your machine are located. Some machines have a user simulation mode where the user can activate an automatic wire cleaning routine. When your when your expensive coper guy comes out, he may just do what you could have done and charge you £100 for the privilege!

Black Lines or Spots on Scans and Copies

Firstly, we dont’t want to teach you to suck eggs. But there is a huge difference between the processes involved in printing and copying and understanding a few simple basics will help you to diagnose and solve silly issues like this. Canon printer support is not much different than support on any printing device including copiers and scanners. The same issues will arise on a Sharp copier, Samsung copier, Xerox or Lexmark printer. The only difference is how the machine comes apart and how service modes are accessed and configured. All laser machines use toner and developer. When it comes to scanning most machines look more or less identical. There is a document feeder to feed through documents automatically, and a platen glass where single sheets, books and magazines can be placed for copying. Now, if you are seeing black lines on your copies first make sure it is the scanner and not the print engine. Perform a print or print an internal report and then a scan from the document feeder to email or USB. If the line is visible on your PC when looking at the scanned document, but not on print outs, then you scanner is the culprit. When you lift up the whole document feeder to expose the big glass window or bed of the machine, you may notice that there is a smaller piece of glass (known as the slip glass) to the left of the main glass. This is the glass that the optical unit uses to shine through and onto the documents when they feed through the document feeder. Not the big sheet of glass. If you are seeing lines then there is probably dirt or Tippex on that piece of glass. I have attended calls where the customer swears they have cleaned the slip glass but they have actually cleaned the large sheet of glass which is gleaming bright and clean. But, the slip glass is caked with Tippex. Sometimes a little piece of glue gets stuck onto the glass and is stubborn to remove. You have to look closely at an angle to see if you’ve cleaned it properly. Sometimes you will have to scratch the dirt off with your fingernail. If there is jsut one small spot of dirt on the glass that may be hard for you to see, it can cause a continuous dot all down the page, which actually translates into a line. Remember a document is scanned and recreated one horizontal line at a time and each line consists of dots. Having a randon dot on one spot will cause that to replicated right down the page. Black spots and other weird shapes caused by the scanner will usually only be found when you are using the main glass. Cleaning that glass should help. But when all else fails, you’ve done your best now call out the Canon printer support guy from east London. Well, anywhere actuually. You will not find a copier company that will refuse a job in west London because they are located in Leyton.

Calling for Canon Printer Support Can be Expensive

Calling Sharp, Xerox, Lexmark, Toshiba or Canon printer support companies can be very expensive if you do not have a contract. Always try to get into a service contract with a reputable copier company to save you the headache of paying for one-off call outs. It’s also worth noting that your machine will probably be in better condition if it’s covered under a maintenance contract because the service company will want your machine up and running to specification so that they can maintain high profitability for your machine. They would rather visit just a few times a year to fully service and keep your machine running smoothly, than to leave it limping along on two cylinders and having you call them out every 3 or 4 days for jams and error codes. When you don’t have a contract you will call out the copier guy to clear a jam and go. The machine may work for a while but with no preventative maintenance it is sure to fail again soon, especially if it is a busy machine.

Tip: Using compatible toner and drum products for your Canon copier will invalidate any warranty. All other manufacturers operate in the same way. Cheap is not best when it comes to copiers and printers.

You have been warned!

New Site Ready For so Much!

Welcome to our first blog post. Our website intends to bring you as many service manuals as we possibly can. So far we have uploaded HP, Canon, Kyocera and Samsung service and parts manuals but we are looking to increase the number of manuals from a few hundred to a few thousand over the coming weeks and months. We will also be working closely with Canon Service Manual to bring lots of solutions to many copier and printer faults we come across on a variety of manuafacturers. We will be linking to posts such as this example of a problem with a Canon irac5235i with a blank screen.

The author has over 30 years of experience on Fax, Print, Scan, Analogue and Digital Copiers across a variety of manufacturers including Xerox, Canon, Panasonic, Sharp, Kyocera, Ricoh and Samsung. You will probably find a Canon and Kyocera bias at the moment, with a bit of Ricoh, due to current contractual obligations dictating that. Every attempt will be made to encourage user participation and along with our Facebook partners over at @Canon Service Manuals, we will be putting together a chat-type technical forum and mobile app where engineers can get immediate help from their smart phones by linking to other engineers across the globe. Well, that’s the plan! How long it will take to get us to that stage is anyones guess. If you are interested in contributing for the greater good, by beccoming one of the first members of such a forum and/or technical chat app then please email us at support (at), expressing your interest.

We can provide practically any Canon, Ricoh, Kyocera or Konica Minolta printer/copier parts manual by using our Manual Request Form. Other manufacturer’s manuals will be added to our catalogue as we get them and, of course, you can still browse all of the other manuals from our current stock too.

Thanks for stopping by and please let us know if you have any ideas for our site that would make your life out there with copiers any easier. It’s real in tha field!
