What i will do if toner disposal is blink and eror E31 i hope you help me. we dont have contact technician for this kyocera K1620

The error message "replace toner" indicates that the printer's toner cartridge needs to be replaced. However, since you mentioned that you already replaced it with a new one, there may be a few reasons why the error message is still appearing:

1. The toner cartridge may be defective. Even though it is new, it may have a defect that is preventing it from being recognized by the printer. Try replacing it with a different toner cartridge.
2. The toner cartridge may not be compatible with your printer. If you are using a non-genuine toner cartridge, it may not be compatible with your printer. Try using a genuine Kyocera toner cartridge.
3. The toner sensor or other hardware may be malfunctioning. In some cases, the error message may be caused by a malfunctioning toner sensor or other hardware issue. In this case, you may need to contact a Kyocera service technician for further assistance.

I hope this helps!

One button being stuck could be the issue. It could also be that the panel is going out.

For stuck buttons:

TURN MACHINE OFF
UNPLUG MACHINE
Spray alcohol on buttons (Do NOT soak the panel)
press all buttons repeatedly

NOTE: This is a quick fix. If you do not want to damage components, call an experienced technician.

Hi and Welcome to Fixya!

E31 simply means - Waste Toner Reservoir Overflow Problem (when the total number of copies is more than 100K sheets). After E31 is displayed, 1000 sheets may be copied before shutdown.

Hope this helps!

Shake the process unit from side to side and turn the power switch off and then on. If the problem cannot be solved, replace the process unit. After replacing the process unit, turn the power switch off and then on. If the problem

cannot be solved, replace the waste toner sensor or the engine board (KP-5061).

this is an error code for slow warm up you should pull the fuser out and check the thermistors and condition of the rollers. sometimes the thermistors get caked in toner so they cant read the temps correct. if you take the unit apart you should be able to detect the toner build up. a soft clothe and some WD40 may be able to clean it off but be ccareful as too rough may clip ther resistor off.

Call the Kyocera hotline they have technicians you can speak with over the phone who can help you.
