Error code F 26-3 on Konica 7022
Sir/mam, you might have a bad drum density sensor or it was not cleaned or was destroyed by static electricity, if a vacuum cleaner was use to remove the old developer, NEVER use a vacuum cleaner for that procedure. Remove the drum and will see a small sensor near where the cleaning blade sits need to clean it replace it. Worse case the main control board is bad that what sensor talks to .Was the L Detect procedure run after the developer was replaced, and before you replaced the developer did you clear the developer counter, to let machine know it has new developer, because clearing the counter is the only way the copier has new developer, did you clear the counter for the new drum? The machine use the counters to determine voltages for certain assemblies. If L detect was not run and copies or prints where made get new developer and start over. Btw, I’m available to help over the phone in case u need at
