Sharp code f2-64

The code refers to the black toner supply fault. This is usually caused by the toner compacting in the toner cartridge. There have been a couple of instances where the plastic strip remains when the cartridge is replaced. If this isn't the case then the solution is to remove the black toner cartridge & gently but firmly tapping the toner cartridge to break up the compacted toner. Re-installing the cartridge & turning the machine off & then on should reset the error code. If the code remains it may also indicate a faulty toner cartridge & this can be proven by replacing the black toner cartridge with another one. If, after replacing the toner cartridge with a replacement, the code re-occurs then this could indicate damaged toner supply gears which would require a technician to verify, but the most common cause tends to be the toner cartridge is at fault.
Hope this helps.

HP 2840, black ink drum q3964a

Hello, these printers tend to be finicky.

In other words, just replace the black toner. When the printer says its low, or empty, regardless of wether or not it is, just replace it.

Replacing the drum, when it says black toner needs to be replaced will do nothing to rectify the issue.

Buy only HP Toner and Drum cartridges for this printer. Do not try to refill toner cartridges, and do not reset drum. You will only end up destroying your printer in the process.

Ricoh SP C410DN

Unfortunately the newer ricoh equipment may include a chip like the HP toner. This allows the printer to track the usage so the printer can "intelligently" determine how much toner remains in the bottle. The chip overides all other factors on the remaining toner. Hence, if the chip "thinks" that the toner bottle has little or no toner left, it will give you a false toner low message. Presently, you can only replace the toner with a new bottle.

System Fault

Black toner problem.Probably You have low toner sensor defect.
But try first to vacuum and clean black toner dispenser.You must vacuum whole path wich is used to transport black toner to developer unit.Then if printing B/W print only, you must print 10 full color sheets every 100 copies.
