Hi there,
If the display shows drum error you can try cleaning it by following the steps below:
1. Open the front cover. 2. Pull the drum (black) and toner (gray) towards you, put a little force on it. 3. Remove the toner by holding down the tab on the side of the drum, then pull the toner out. 4. Use a dry lint-free cloth to clean the roller inside the drum unit. Make sure to remove any excess toner from it. 5. Put the toner back to the drum, make sure that it clicks, Reinstall the drum and toner back to the machine, 6. Close the cover.

If the display still shows drum error, go ahead and do the drum reset.

1. Open the front cover 2. Press the Options button on the control panel 3. The display should show "Replace Drum - 1. Yes 2. No 4. Press 1 to reset the drum count 5. Close front cover. The display should show the date & time
If still it shows drum error, The drum unit needs to be replace. After replacing the drum unit, do the drum reset again,
Hope this helps.

When power on printer DCP 135C an error disply as clean unable 46.see troubleshooting and routine maintence chapter in user guide

I've run into this error before, and basically it means something is stopping the carriage from moving.
If you are unable to find out what is causing the carriage to not move, the printer is not economically feasible to repair and will need to be replaced.

Drum error. dont have user guide. how do i troubleshoot? tried replacing drum but still says drum error.

If the drum is used up you open the front door and press menu or options and tell it it's a new drum, otherwise you clean the metal contacts on the sides of the drum and inside the printer, and run the blue tab back and forth about 20 times. If still drum error you may have a bad power supply.

Try this, take out the drum and check if there is any scratch on it. If it is then change drum.
The other problem can be dump in the scanner unit when u place a paper to copy, try to check it.
