When is the last time the developer and drum where replaced? When the last time was a PM done? Very 250,000 copies a PM must be done? Which replaces the Corona Wires, Developer, Drum, Corona Grid, Web roller for fuser (Hot Part). Also during the PM the Tech should clean the toner out of the Waste Toner collection unit on the image unit. also clean the area around the drum and developer roller.
Did you clear the counters before you replaced the drum and developer? If not Replace the drum and developer again. This time clear the counters for the drum and developer before. This done as such
Have you had the developer and drum replaced or does the screen say Replace PC Drum? There are certain house chores the copier does before "Ready to Copy" it is waiting for them to get done equals "Please Wait". One big item is making sure the developer and toner are properly mixed inside the image unit underneath the drum. Might want to have the developer replaced and drum/cleaning blade normally done all together, then run the F8 procedure and make sure the counters where cleared Did you recently replace the drum and the developer if so did you clear the counters for the drum and developer. IF not then the copier thinks the new drum and new developer are old. Copier works on the counters that how it know it got a new drum and developer. Get new develop and new drum and have it installed correctly, Counters are clear before the unit is yanked out of the machine, then you remove the image unit/drum unit replace the developer/drum and cleaning blade. (DO NOT USE AVACUUM CLEANER WHEN REPLACING THE DEVELOPER static electricity can destroy the sensor located below the developer unit. Then reinstall and RUN F8. Make sure the fax line and Ethernet cable is removed can't print anything until the F8 is run. Or you start over with new developer and new drum
Automatic toner density sensor code the toner to developer ration is incorrect or the sensor is bad sensor located under the developer unit which houses the drum, when was the last time developer was replaced and the required F8 run??????? Get new developer, first
When was the last time the developer was replaced in the developer unit? If it has been replaced then you might have a bad ATDC (Automatic Toner Density Control) sensor Located right below the developer unit. If the developer was replaced when it was done was a vacuum cleaner used? IF so the static electricity from the vacuum clear destroyed the sensor, NEVER USE a VACUUM cleaner to remove the developer. Also when the developer was replaced, was counter cleared to tell the copier developer was replaced, the copier use the counters to determine certain voltages for certain assemblies, if not image problems and codes can appear. Finally was the F8 run after the developer was installed before any prints or copies made? If not buy new developer and start over, counter is to be cleared first, then developer replaced, then F8 run.
When was the last time the developer and drum where replaced? Does the machine say "REPLACE DRUM in the upper left corner of the operation screen? More then likely your drum and developer need to be replace if not those then the DEVELOPER CARTRIDGE NEED TO BE REPLACE when was the last time that was replaced? Every four drums the developer cartridge needs to be replaced. When the developer was replace was a F8 run from service mode?
What color is the blue line showing up in??? If it is a green color there is a problem with the yellow drum or developer > I the color is a purple color then there is a problem with the magenta drum unit or developer unit.... Odds are you may need a service tech to come out & do a general cleaning...... Good Luck
On a Sharp AR-201, the developer light comes on when 50,000 pages have been made since the technician (or factory,) last changed the developer substance and reset the counter. A tech should come out with a Preventative Maintenance kit because training is needed to remove the developer substance safely as well as to clean the optics, interior and inspect the fixing unit, drum and cleaning blade and vacuum out the copier. You should call for service and tell them the developer light is on so they know to bring a kit. And yes... I am factory trained on this model. Retired now.
Hello, How many copies do You have? ( press 123 button ) If You have over 150 000 copies, probably you need to change the Bk developer unit. It can't be changed only the developer, but the whole unit.
This is quite expensive copier for maintenance. If the time comes for Bk developer unit it means that you will soon have to replace Y, C and M developer unit. Also when did you last time replaced the drum unit?
Be sure to post back the copy counter, for detailed instrunctions...
Regarding color adjustment, before that you need to clean the copy optics ( glass beneath and cis sensor ), then in user mode ( asterix key ) under copy settings find color adjustment and perform it. It's like 5 sheets, beeing printed one by one and which you need to scann over copy glass, but in most cases it doesn't helps...
If You want service manual you can write on firstname.lastname@example.org
We have over 50 of these printers and a few have had the magenta bleeding problem. On everyone of them the problem was corrected by going to the clean developer function under Maintenence from the Menu and choosing to clean the magenta color. Usually have to run it a couple times but it has always corrected the problem so far.
