Ricoh MP 7500: blurry text After Idle Period

[Mohammed Maloul]

I’m experiencing an issue with my Ricoh MP 7500. When the printer has been idle for a long time (e.g., overnight), the first batch of printed pages often has blurry text or like dragged toner in certain areas as shown in the image. However, after printing a larger number of pages (approximately 150–200), the problem disappears, and the print quality becomes normal.
i checked the fuser temperature and found it normal.
i have two pther printers mp 9002 which does the same problem but i have also mp 6001 which does not have the problem.
any thoughts?

I know very well this issue.
-Tear down the drum section
-Vac everithing
-Take the drum cylinder, and clean more time With a cleaned soft rag and alcool.
-Replace the developer
-Connect the heater connector on the PSU in the rear of machine.
-leave the Power connected, and the machine on, during the night

Moisture buildup on the surface of the drum. I User Tools - System Settings - Timer Settings - Weekly Timer: Monday - Sunday you can set the 7500 to power ON 30 minutes to an hour before you are going to start using it. This will warm the entire upper half of the 7500 and get rid of any condensation.

Check the screw that holds the flange that the flywheel is attached to it falls out sometimes

Hello

We know this problem very good, and we are fighting it for almost 5 years now. The problem occurs as you said after an idle time and it affects EVERY machine from the old Aficio 2075 to our relative new MP 7503. No problems for tghe other ones like MP 5054 or similar
We do the same things as LUCA72 wrote, and we clean the drum with a car polish like NU FINISH , or alcohol .
We experienced this problem since Ricoh changed toner to the TYPE MP 9002. Of course the environment is very important.We are in Sicily here and in summer we have very hight temperatures and often a high air humidity, same in Winter. It's a good idea to connect the tray heaters, and turn on in SP mode every fan (drum, toner bottle fan, etc etc).

Codex says exactly what happens and we lost many of our productive customers. They are Konica's customers now.

I read theories about moisture and/or "ozone buildup" when this issue occure. Make shure the room enviroment is OK and all dust/ozonr filters and air channels are in good shape to ensure proper airflow inside the engine. Playing around with the weekly timer like suggested by slimslob sounds like good hint, too.

I've always had good luck by plugging in the heaters in the rear of the machine. You've got to plug them in at the power supply, they are not connected at the factory.

the "condensate" drum is the effect, the disconnected heaters are the cause.
if they are not connected after a couple of months the problem returns
