This is likely a failed fuser unit that will need to be repaired or replaced depending on page count. You can remove the fuser to look and see how it is. Unplug printer, turn printer around so that you are facing the back. Open the back where you would normally open to either remove jams or have straight path printer. Where that door swings on the left hand side there is a finger notch. Press in and remove the back door. On either side of the fuser is a blue latch. Squeeze these and pull on the fuser. Look into the fuser from the side where paper goes in and check the condition of the upper brown roller. If it is dirty and toner and it looks like there is toner baked on it then is definietly the cause of your problem. If your page count is over 150,000 I would just go ahead and install a maintenance kit in the printer.

When printing, the top half of page prints normal... bottom half of page very faint...


Your ink cartridge has about 9 very small nozzles that spray ink to complete a letter the upper nozzles complete the upper half and the lower half is done by the lower nozzles. The lower nozzles are stopped or clogged up by dried up ink or the control resisters in the firing circuit are burned out. some times you can unclog the nozzles by soaking the lower part of the cartridge in hot water for a half hour and drying it well ,replace it in the carrier and try it again. However you will lose a lot of ink and it may be more prudent to replace the cartridge.

The print is faint. The lettering on the excel spreadsheet is Arial Regular 10, colour - automatic and normal font. However, the printed copy appears grey rather than black. Toner cartridge recently...


normally you go to printer settings and look for where it says page quality. make sure the page quality is set to normal or fine. this will make it black. if it is on a setting lower than this it will cause the printed document to appear grey.

cheers.

Faint grey lines Every 1/3rd of a printed page


This is the test to determine toner or fuser issue.
Print a test page
When you hear the paper feed into the machine open the top to stop the machine
Remove the toner cart.
You should be able to see the page with printing on it. (This is before the page hits the fuser)
If you can see the smudge or marks on the page the problem is most likely the cartridge or cleaning roller but NOT the fuser.
If the page is clean the problem is most likely the fuser.

A940 printing issue


hmm..now..that sounds more like a software issue, than a hardware issue. Can you check on all version updates for the software from MSoft, and ensure that the drivers for your printer, by application, are up to date. From what I'm seeing, this MAY not be a printer issue.

and, if you want, we do this sort of service call remotely. see my link here for more on that.

There's a profile link on top right, that may be of some value, if this becomes unsolvable from your end.
