I have a Kyocera Mita 1530 copier. We changed the toner and began getting a error message of C710. I tried the solution posted on your website of entering 1087 1087 then 131 press copy set toner to 155 turn off then on. However, now it still has the C710 and the maintenance light came on as well. What can I do?

Hi there
I have found various documents which may help you with this problem and possible future problems. This page:
Error Codes Kyocera Mita KM1530 Code C710
can find any code connected with Kyocera mita machines by changing the machine and the error code in the appropriate drop down menus. C710 is identified as:
Description Toner sensor problem
• The sensor output voltage is outside the range of 0.5 to 4.5 V during toner control.
• The toner sensor control voltage cannot be set within the setting range when maintenance item U130 is run. Causes Defective toner sensor. Poor contact of the toner sensor connector terminals. Developer problem.
Another page showing error codes and their meanings is here;
Kyocera Mita Error Code Messages
and this confirms the above.
Also the link below takes you to a Kyocera web page where you can download various manuals for this machine (KM-1530). By changing the product in the drop down menu to KN-2030 you can get similar manuals for this machine.

In your question you mention "Compatible KP23153 Black Toner Cartridge 106153" and that led me to wonder if the compatible cartridge is the cause of your C710 error since that is toner related.
Might be worth trying an original cartridge to see if the error goes away.
Hope this is helpful, if so would you please register that with Fixya
Cheers

Try using a small soft brush to brush it off while using a good hepa filter vacuum to remove the toner at the same time. Wear a good breathing mask to protect your lungs!

A J10 shows up if there is no feed from the upper paper tray. Check the operation of the paper feed clutch for the upper drawer.
Good luck,

replace the toner sensor

When AP flashes the toner is being replenished inside the copier. Wait a few minutes. You need to refill the toner.

C 710 is a Toner Sensor Problem

Defective toner sensor - Replace toner sensor

Poor contact of the toner sensor connector terminals - Reinsert the connector. Also check for continuity within the connector cable. If none, repair or replace cable.

Developer problem - Replace developer.

it means that toner cannot enter the developing section of the copier, all you have to do is remove the developing unit, then pour it with enough toner, the problem will be solve.

C170-Toner sensor/Developer Error
check usual suspects Sensor, Wiring, Developer material, connectors.......

Your problem could be one of several things:

1) The Carrier (iron filings) inside the imaging unit is deteriorated and needs to be replaced.

2) The Toner sensor inside the imaging unit may be giving an incoorect reading, due to be faulty or because of old toner/carrier mix blockage close to sensor. Give the imaging unit a good service and replace the carrier.

3) The wires behind the black cover of the imaging unit have been picnhed and is shorting on the metal plate

4) The main PCB of the machine could be faulty

press 1087 1087, then 131, press copy and then set toner level to 155. turn off machine and on again.
