I have a Konica 7022 copier how do i remove the paper trays

This sounds like you have a piece of paper behind tray one.
1. Turn the machine off
2. Take out tray 1
3. Remove paper
4. Insert tray
5. Turn back on


If that doesn't help, you have and issue with the paper pick up motor. This is 99% of the time not the issue. The paper behind the tray is most likely your problem.

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.

Hi,
C-0206 relates to tray 3.
With the copier turned on do the following
Open paper tray 3, remove paper, close tray, open then shut front door, load paper into tray 3 - hey presto!!
If the fault comes back you could have paper stuck behind the tray or have a defective lift up motor.

There is toner/starter spilled onto a sensor near the drum, it mite just need to be cleaned, this sensor monitors the drums abililty to develope a image, if the cleaning does not work it mite be the sensor or the drum. The drum needs to be removed to clean the sensors.

i have a konica 7022 it say call service code F-35-3, what's wrong with it, help me.

How about this, if you look what paper tray are avaible from the display pannel, is there a matching size paper tray or is the tray you are trying to use another size then lets say LTR. Is it a different size, if so you may have paper jamed behind the paper tray causing a different paper size, if so remove the jamed paper..... Also, the other suggestion are good as well.
