chk first drum unit if it good condition may be toner defctive /clean charger

the buttons stop working because the internal pressing are crash and you should replace it or join it by welding. but first of all you may blow the panel it could be some dust.

When the toner supply belt is broken or displace than toner not supply from the cartridge in the DV unit.You shuld check this drive section and replace new one.I wish best luck.

Kyocera 2050 add toner error problem

Are you using an after market toner? Sometimes the non Kyocera toner causes light copies?

you have to check the duplex unit on the machine itself.

I’m happy to help further over the phone at https://www.6ya.com/expert/mustafa_06f84c65ab5cc745

Is one side lighter then the other side of the copy? Meaning uneven copy darkness? If so, I believe the problem is that one or both sides of the drum cartridge and the developer are not connected correctly. The two parts need to be close togather to make a nice dark copy. This model has a very wierd drum unit and has a defect that one or both side of the drum unit locking tabs break and you get very light or blank copies. It's some what coastly to replace the whole unit... That would be a worse case.... If it is just on one side you might be able to push on the cover on the side that is light. If the copies come out better. One side is broken..I would fold up some paper and make a wedge to push the catridges closer. Good Luck
