Error code cf30 in toshiba 3511 what its mean and how can fix it


(CF30) - Reference plate detection voltage abnormality: The output
value of the color auto-toner sensor against the reference plate
is out of a specified range at the light amount correction during
an auto-toner adjustment or when a print job has finished.

Your color auto-toner sensor and reference plate are located under the input tray cover on the left side of the copier when you are facing it. It is on a bracket that hangs down into the copier and sits close to the revolver inside the machine. It is an optical sensor and if either it or the reference plate get stained with toner it will give you this error message, you may attempt to clean them with rubbing alcohol.

This error message may also occur if the solenoid that drives the reference plate is faulty so you will need to check that as well.

I would sincerely recommend that you get an authorized toshiba technician to take a look at the machine for you as this is a fairly difficult problem to fix right.

WHAT IS DENSITY SENSOR IN LASERJET 8500


The Density Sensor is located inside the right upper door and senses the colour calibration pattern for each colour formed on the transfer drum during a calibration cycle. Press GO. Print a configuration page and then troubleshoot as an Image-quality problem as instructed in the user manual. Check the transfer guide for cracks and replace if necessary. Check the event log for errors numbered 54.00.0<X> the X indicates, 5-sensor abnormality, 4-Cyan, 3-Magenta, 2-Yellow, 1-Black. The last 3 error codes should be seen on the Configuration page.

Our Trusty steed HP 8500 has just started to print a thin twin line and other spurious marks on the top side of prints. Today i replaced the drum / fuser / other bits but no difference any ideas?


I have looked at the manual but there are so many possibilites! You can download the manual here and go to page 148 (PRINTING QUALITY PROBLEMS).

Initially I would follow the directions for clearing drum related errors:

Dark or white lines or streaks in all colors, including black.
Print the configuration page five times. The defect should clear
with continued printing. If the defect does not clear, turn the
printer off and on to reset the printer’s density calibration. If the
problem persists, replace the imaging drum. For more
information on replacing the imaging drum, see the installation
guide included with the drum kit.

Then clean the density sensor.
To clean the density sensor
1
Open the upper right door.
2 Use the brush located next to the
sensor to remove all toner particles
from the sensor.
Note
You can also use a hand wipe to clean the
density sensor. To prevent scratches on
the sensor, do not use any paper products,
such as tissue or paper towels, to clean the
sensor.
3 Close the upper right door.

It could possibly be a problem with the transfer drum.

I am sorry this is not of much help!

The sensor it refers to is the density sensor located inside the machine via the right hand door. Open it and clean the large sensor in the middle. If this doesn't work then clean it with a soution and a soft cloth.
