How do you fix density shutter error and sensor calibration error on OKI C9650 Printer


The shutter protects the density sensors and keeps the windows on the sensors clean, until they wear out. Replace the shutter assy (part number 42755401) and clean the sensor windows.

If this doesn't solve the problem, you may be at the beginning stages of a broken gear for the top cover mechanism that protects the LED printheads when the cover is open. As a test, you can remove the 4 black protective covers from the printheads and see if your machine will calibrate itself. If it does, I recommend leaving the protectors off and just be extra careful of the LED printheads when you change toners...

Dear Sir(s) I have an OKI data OL400e the problem is "Message --Cover open" even i close it well Please advice Thanks


Hello,

had the same problem. It is easily fixed.
On my printer a OKI C5750 is had to main covers, at the front (which you have to open to fix a paper jam) and a big cover on top (which you need to open to replace toners).
On the left is a piece of plastic which (when closed) presses on a switch.
When you open both covers, and close the top one, you can see it on the left when it comes down.

You can easily remove the error (only for a brief moment) by prushing the shining metal switch to the back.

But the problem is that one of the rollers is in a wrong position.
So just take a flat screwdriver and press on the bottom roller, and it will click and the problem will be gone when you close the covers.

My OKI 5200 is saying it has a paper jam open front cover there is no paper jammed and i have looked everywhere for a problem and cannot find one. Still it won't print until the paper jam problem is...


Mine did the same once and although at first I was convinced it was the printer reading incorrectly, in the end, after opening all the parts that open up, I did find a sheet of paper wrapped around the rollers at the back.

Oki c7300


Error 051 is a CU fan error.
It is solved by first replacing fan then the CU board.
I would call the seller or 1-800-OKIDATA
If you're comfortable with a screwdriver I would take the cover off
and look at the fan to see if anything is obstructing the flow.
