The sensor that detects the closed cover is damaged or not functioning. As you do not state what printer you have I cannot tell you an exact fix. Typically there is a plastic tab on the cover that engages a sensor when closed.

SOURCE: Low toner advise keeps on after changing toner and/or printing

Have you tried to unplug your printer and plug it back in, that will force the printer to re-check all its settings and it should notice that the toner is now full.

Error in Cover Sensor (PS14) in M Toner Container

Description Unable to detect opening of the Toner Container Inner
Cover when removing the Toner Container.
Remedy Identify the cause of the error whether it is due to link
mechanism to open the Toner Container Inner Cover or
problem at the Toner Container Inner Cover Sensor side. ?
1. Perform the user mode (Adjustment/Maintenance>
Replace Specified Toner) to check if the Toner Container
Inner Cover opens normally (damage, slide of shaft area,
etc.). ?
2. Check if the Toner Container Inner Cover Sensor is
soiled and the installation of the sensor. ?
3. Check the service mode (COPIER> I/O> DCON> P024
bit9) to see that the output value of the Toner Container
Inner Cover Sensor is changed normally when opening/
closing the Toner Container Inner Cover. ?
If it is normal, the value becomes 0 by rotating the Set-on
Drive Shaft with the attached tool and opening the Toner
Container Inner Cover. When closing the Toner Container
Inner Cover by hand, it becomes 1. ?
3-1. When the Toner Container Inner Cover is not opened
although the Set-on Drive Shaft rotates, check the drive
system from upstream (Set-on Drive Unit -> Hopper Unit
-> Bottle Base Unit -> Toner Container Inner Cover Unit). ?
If it is damaged, replace the damaged part and then
perform step 5 and later steps. ?
3-2. When the output value is not changed normally
although the Toner Container Inner Cover can be opened/
closed, check the Sensor Harness (to see if the harness
is caught, disconnected or physically removed, *including
the Relay Connector). ?
If there is no problem, replace the sensor. After checking
the output value in step 3, perform step 5 and later steps. ?
4. If the problem is not solved by replacing the foregoing
parts, replace the Drum Driver PCB (UN4) and then
perform step 5 and later steps. ?
5. Clear the error in service mode (COPIER>
FUNCTION> CLEAR> ERR), and then turn OFF and then
ON the main power. ?
6. Replace the toner (reinstall the removed Toner
Container) at least once in user mode (Adjustment/
Maintenance> Replace Specified Toner), and check that
toner replacement can be performed normally.

I had the same problem and it was the pick-up roller that was at fault. You can buy a new one for less than 20GBP or do what I did. Take the old one out and reverse the rubber. There are plenty of online tutorials on how to change the pick-up roller - the first one you remove. It's a two minute job. Reversing the rubber is easy. Just prize the inner clip out of the roller and put the rubber back on with the shiny side out. It worked first time and no more print errors.

My photocopy machine shows code C0070


Power off the machine. Then remove the toner bottle be careful the hole might be on the bottom toner is going to everywhere. Then close the toner cover and turn on the machine.

If THE KUNB on the side of the bottle is damage put a new one in that KUNB is what the toner motor uses to turn the bottle if it damage you get a code. If that does not work you might have a bad motor or the home sensor or actuator for the toner bottle is bad worse case the control board is bad.

The printer is giving me service error E527 what can be done to overcome this error


Hi Good day!!!

This error message "Service Req E527" means that the toner carousel housing the toner cartridges is obstructed, or is unable to rotate correctly. It can be caused by installing a toner cartridge incorrectly.

Solution 1:Check that the toner cartridge at the front of the printer is installed correctly.

Solution 2: Manually remove all of the toner cartridges.
Close all the covers, and then power the printer off.Open Cover B, and then remove the photo conductor unit (PCU).Turn the toner carousel by hand to line up a toner cartridge with the front of the printer.Open Cover A.If the toner cartridge is not in position to remove it, close Cover A and repeat the steps above.Remove the toner cartridge, and then close Cover A.Repeat all the steps above until you have removed all four toner cartridges.Reinstall the PCU.Close all the covers, and then power on the printer.Open Cover A and Cover B.Check thoroughly for any jammed paper, foreign objects or damaged parts.If you can locate an obstruction, remove it. Then, close all the covers and restart the printer again. If you can identify any damaged parts, there is an obstruction you cannot remove, or there is no change after restarting the printer, then contact Epson for further advice.Reinstall the toner cartridges (Follow the prompts on the LCD display), and then test the printer.

The scree reads change drum soon. what does it mean


The drum is the part of the unit that actually does the transfer of the toner onto the paper. Each toner cartridge does about 2,000 pages and the drum needs to be replaced with the ~6th toner cartridge change (varies with use). Order part DR-250 from Brother or any office supply place that would carry the part.

To replace (wait until print quality decreases or it reads change drum now and stops working). Turn off the unit and let it cool. Close the document tray and the extension and open the top cover. Remove the drum carefully and place it where the toner will not spill. Remove the toner cartridge (if it is still good) and set it aside to put in the new drum.
Wrap the old cartridge up and dispose of properly (not in the domestic trash). Keep the new drum out of the light (keep it sealed until needed) as much as possible. Insert the toner cartridge in the new drum. Then insert the unit into the Fax machine. (Hold by the handles) Close the top cover and the starter sheet should be ejected by the machine.

I hope this helps.

Drum light on Ready light on Alarm light on Data light on


Alarm and Data lights on together is from low toner. If shaking of the toner cartridge is not helping, change the toner.
Drum light is usually on because of the print counter. If the print quality goes really bad, change the drum and reset the counter by holding the front button wile the front cover is open till all lights come on. Release the button and close the cover.
If just Data light is on, check the print ques, some jobs might got stuck there.

IBM infoprint 1312 toner and error light.


If both Lights are solid, it means that the top cover is still open and the toner is low. Please make sure the top cover is closed all the way. If the toner light is blinking and the errror light is solid, it means there is a toner cartridge error. Please try a new cartridge. If that solves the issue, then you should return the damaged one.
