May not be worth repairing.

Error code relates to the fuser unit.Suggest that it is replaced.

In most cases the printer driver software can have errors while being in use or is shut down. So to reset remove your printer from the PC and uninstall the printer software. Now reinstall the printer software and then connect the Printer ONLY WHEN PROMPTED, to be detected as a new hardware as it will be installed. Now check the printer properties to see the ink levels.
Activate head cleaning before a test is taken. Sometimes it is possible that the head is not reacting to the need of the PC command or can be an issue with ink drying or poor ink cartridge contacts. Sometimes the power supply unit must be checked as a poor SMPS unit can deliver low voltage and cause issues to the printer function. Check all the leads and connections of the mother board , the tags to the ink cartridge. Also check the mechanical settings of the ink cartridge , if jammed or tight remove motor and manually free the drive before it is set back.

Thank you for using Fixya

Call service message 6000 in Kyocera is a fuser error code. The fuser must have gone bad.

Try the feed tires in the tray first. More than likely the paper is not being picked up and causing jam message. The separation roller also has a hub on it to prevent a second sheet from feeding. Sometimes these start to lock up ,a little oil on the hub sometimes relieves some of the tension.

Hello, the code 7000 refers to the toner motor, but if you check my blog and there I have the full service manual. I hope you let me serve a Comment

It is a "mechanical error". The part after the colon is the number of pages printed. It's probably worthwhile taking the trays, toner and cartridge out and opening all the access doors and checking for something obvious before calling in an engineer.

that is a fuser code check the fuse
