Error 7410 - Drum unit non- installing error

The drum unit is not installed or not installed properly. Install the drum unit (See page P.1-5-10 of your operation guide). See image below.The numbers after 7410- are the number of pages printed on this printer.

dots are usually always caused by the drum..drums are very easy to replace..(you don't even need a screwdriver)
here's how..
remove the unit that the toner sits into..it's called a process unit..comes out as a whole with the toners...
next open left cover..
remove waste toner bottle. (drum sits right above it!!!
next remove drum by pushing on grey button and pulling drum
out the left side of the printer.

as far as the jam message you might need to replace tray feed tires located up under the machine

Easy. You have to seek the problem at the left side underneath the the gears.Turn it to the bottom.There is a protruding metal peace. Bend it back to stand vertival. It will slow your problem, but if not feel free to ask!It helped to me.

I've never heard of anyone attempting what you describe, but I'm concerned that the new coating will not be even enough for a satisfactory print, even if the drum will function in the static retention.Replacing the fuser is recommended:http://www.redstartprinters.com/fk-320fuserunitfs-3900dn4000dnprintersfreegroundshipping.aspx

have to change the values one by one.Not in the maintenance manual for factory settings

Go to the maintenance menu and do a drum refresh. else try to clean the transfer roll

Your drum unit is not correctly installed. Reinstall the drum unitThe drum eeprom is not communicating correctly

open printer front cover and remove drum unite ,two side screw open two side spring **** two side open drum
if you are not possible it then buy a new one unite in your service authorized delar

Sounds like a Engine firmware failure. The clue is the low page count (the 00007).
You will need to upgrade your firmware and contact your local Kyocera sales comany to get a patch to correct the missing serial number and MAC address.

Toner is low

Hi,
This problem is caused by a poor contact in the fuser connector terminals.
Check both sides of the connection (in the printer and fuser unit) In most cases we will find small pieces of paper inside printer connector causing poor contact between printer and fuser unit connector.
Hope i was of any help. If i was, please rate me.
Thank you.

The 7410 indicates a drum error (see below) the 0163053 is the number of prints made by the printer. The drum was most likely knocked loose when installing toner.

Very weird message! Pull down the by-pass tray in the front of the printer and insert a sheet of paper , then print.

check the sensor of the door

Hi there maximum time we found it is a the head problem. The print head is what the cartridges sit in inside of the printer. For resolve the problem please follow these.
Open the printer and wait for the carriage to slide over. Some how if its not come then Unplug the printer & Manually slide the carriage. Now Remove the ink cartridges from the print head & Use wet warm cotton swab or use alcohol to thoroughly clean the print head. Repeat this until there is no ink residue coming off on the cotton swab. After finished it make the head dry then fix it back. Now Try to print something now If that does not work then follow the next step.
Remove the printer data cable & restart the PC & printer. Then fit back the data cable & turn on the printer. Hope that's start working , if no luck then Uninstall the printer driver & restart the PC & Printer both again. Now install the driver of the printer and connect it with PC ,Turn on printer & go for a test print from the printer preference. Thanks & waiting for your reply.
