My FW780 will not make copies. Only white paper comes out after attempting to make a copy. No toner exhibited on the paper. I get no 'low toner' messages or warning lights on the control panel. What gives??

If your Ricoh MPC 2011 is printing or copying blank pages when trying to print or copy in black and white, it is possible that the toner cartridge is either empty or defective. Here are a few steps you can take to troubleshoot the issue:

1. Check the toner level: Check the toner level in the printer to ensure that it is not empty or low.
2. Replace the toner cartridge: If the toner level is low, try replacing the toner cartridge with a new one to see if that resolves the issue.
3. Clean the printer: Dust and debris can sometimes accumulate inside the printer, which can affect print quality. Try cleaning the printer to remove any dirt or debris that may be interfering with the printing process.
4. Check the settings: Make sure that the printer settings are configured correctly for black and white printing.

If none of these steps work, it may be necessary to contact a printer technician for further assistance.

remove the toner bottle and make around 50 copies but make the copies in A4 LEF but with open ADF and put a white paper on half of the A4 LEF area for to be the copes half white half black. This must be done for the extra toner that is inside the developer unit to be removed. It must be half black-half white for the machine can print the copies, otherwise it will constantly jams. pit the white paper in the right half section of A4 LEF area and make around 50 copies. But do this without toner bottle inside the machine. After the 50 copies end,print a counter and see does it got better. If is ok then return back the toner bottle and the machine will continue to work. If still the copy is bad then make more copies without toner bottle until the image is clear.

Not at all certain what your question refers to. The Hp Image Runner 400 is a black & white copier. What do you want to do that you are unable to do? Have you previously been able to do what you wanted with this copier, but can no longer do the same? What happens when you try to copy a document? Does the copy come out blank, or all black? Are you getting a large black area on a 8.5 x 11 inch sheet of copy paper when you attempt to copy something that is smaller in size, and therefore wasting lots of toner? Please explain your problem in detail, or no one will be able to help you. Thanks

check cartridge setting how-
check all spring on correct place
check ITR spring touch point
check printer to cartridge touch point

See this. It's for a HP. But the troubleshooting is similar.

Fault on ricoh fw780 ,blinking no toner replace the New tonner cartidge

several possibility of problem are:
- empty toner (you must check it)
- moist paper (solution = the copies which come out blank return to paper case, to use again. it is mean to use not moist paper)
- lifetime of the drum is over.

I bought a km1620 copier. but copied only A4 size paper. No longer paper can not print except A4 paper. how can I change copying system. And how can I count copy. pls. mail me.

A common mistake is that people think that the waste toner needs to be emptied and instead the toner needs to be replaced --- and vice versa. Check to make sure that the toner bottle is not empty. Also, if you made copies that took ( used ) more toner then the machine was able to replenish, the machine has not had a chance to catch up. Place a white sheet of paper on the platen glass and make blank white copies. You may only be able to get 1-2 copies at first but as the device catches up with the toner replenish you should be able to make more. The blank copies you make -- do NOT put that paper right back into the machine. Lay it flat and let it cool, this will help prevent unwanted jamming due to heat build up in the paper. IF you have good amount of new toner in the machine, gently tap the front line ( or rear line) that feeds the used toner into the waste bottle. Sometimes the waste toner will clog and back up into the machine giving false 'waste toner full' message.

You did not specify how much of it it is NOT copying or left off.


Depends on how close to the end it is copying.
Try this make a copy of the ceiling ( open top with no documents and copy) it will give you a black sheet of paper, compare it to your copy, there is a margin of white around the black area this is because :
1- makes sure the toner is falling on the sheet
2- leaves enough room to clear out of the fuser.

Is your print falling in the white area? if so it can be adjusted but there has to be a margin of white around the paper. or it will cause jamming.

Good luck
