How do i clear developer light and serviceman after replacing developer and serviced the machine. Please help Newton

That's a serviceman light and the star (circle of dots) means your machine is due for a developer change.

maintenance reset = crop 20 -01
developer reset = crop 42-01

'Service man:press # interupt and C interupt
enter 24 and then 01 for drum and then 42 then 01 for developer.

Sir/Mam Have you had the developer and drum replaced recently, 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, so that equals "Please Wait". One big item is making sure the developer and toner are properly mixed inside the image unit underneath the drum or next to it depending on the series. Might want to have the developer replaced and drum/cleaning blade normally done all together, then run the F8 procedure/Developer Charge, 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, FIRST? IF not then the copier thinks the new drum and new developer are old. The copier works on the counters that is how it knows it got a new drum and developer. Get new developer and a 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 A VACUUM CLEANER WHEN REPLACING THE DEVELOPER static electricity can destroy the sensor located below the developer unit. Then reinstall and RUN F8/Developer Charge. Make sure the fax line and Ethernet cable is removed can't print anything until the F8 is run. Or you will start all over again with new developer and a new drum.

Also try removing the toner bottle, turn off the machine with the toner bottle out and cover closed turn on the machine when it ask for toner properly place the toner bottle in the machine

It's not developer light.
It is drum unit light and maintenance.
You have to replace the Drum, Blade and Developer.
After changing them you have to reset the maintenance, drum,developer counter.
This procedure must be made by a copier tech.

But if you still want only the developer the code is AR-202D

After you replace developer, press #, interrupt, c , interrupt keys in that order. Display will go off, press 42 print 01 print for developer reset. Press Interrupt key twice and press 20 print 01 print for serviceman reset. Press CA key .

Reset the developer by pressing C-CA-0-C - 83-5

what happens when u run L-detect. Make sure the sensor near the drum sep claws in the drum unit is clean. Any toner or setting powder on this semsor will give u errors while running L-detect.
