Printing Issue - Lexmark T642

Please help,

We have a Lexmark T642 all worked fine but we put in compatible one 64035HA toner and we get 929 error stating "Service Sensor is On".
At some point, before we turned off the printer we where able to get one page at a time.

Thank you so much,

Not a chip error but a mixing rod/pac man gear problem. either way the cartridge is bad....shaking could help as hard toner can cause the mixing rod to bind.

Chip on toner is bad, try puting in old one to reset and switch it with new one, sometimes turning off and on several times helps.

Lexmark T642 print gray though new cartridge


Hello,

The main cause of light print is a bad set of charge and transfer rollers. These rollers are used to put a charge on the paper and transfer the toner to the charged paper. When the rollers get worn out they can not put the proper electrical charge on the paper so the toner does not stick to it as it should. One roller sits under the toner cartridge and on is on top on the cartridge. If you pull out the toner and look inside the printer you will see the transfer roller and if you start to close the lid with the toner out you will see the charge roller come into view. Here are pictures of each one. Transfer roller first.

These rollers come in the preventative maintenance roller kit. This kit is available at the following link. The kit also comes with the pickup rollers.

202.16 ERROR


Hello,

The 202.16 error indicated that something is covering the exit sensor in the fuser assembly while the printer is warming up. This usually is caused by a piece of paper being left after a paper jam. First open the top of the printer and remove the toner cartridge, look inside for a piece of paper, if found remove it. put the toner back in and close the cover and press the "check" button to clear the error. If no paper is found then open the back of the printer and look for a piece of paper in the fuser assembly there, if found remove it. If you find a piece of paper in the fuser you will need to press the "check" button to clear the error and resume printing.

Here is a link to the Lexmark support page on this error.

On a T642 prints out first three sheets just fine but on 4th it never makes it to the fuser. The paper curels inbetween the fusers and toner. 201.32 error


The error 201 means exactly what you are getting;
a paper jam between the printer input and exit sensors.

It is common on these printers for toner to build up on the fuser input guide and eventually gets so big as to catch on the leading edge of the paper,

you will need to scrape the encrusted toner off of the guide.

If the device has done a large volume of printing (say over 100k) it may be a faulty fuser assembly.

PRINTER CUTTING INFORMATION WHEN PRINTING


Make sure you have sufficient levels of ink/toner.

Even if the text seems fine on parts of the page, the drum could be damaged so some parts of the drum is not rolling.

It could also be a driver issue.

Firstly, i'd recommend checking the toner for any damage.

Secondly, i'd update the driver from Lexmark's website.

Lastly, i'd contact support if you've not got a solution yet!

Lexmark t644 error code 917.00


This error indicates that there is a charging problem with the transfer roller. You could start by cleaning the contacts for the transfer roller (power off printer first). The transfer roller is the black foam-like roller under the toner cartridge. Handle it with paper because the oils on your hand could damage it. To remove it, just pry under the far left side with a screwdriver. Lift and pull to the left to remove. If this does not fix it, then you have a more serious problem. It could be one of the arms or the HVPS.
