Print Light Won't Come On and Allow Print

What the heck is a DC1435???

Please can you tell me the model?

This can be caused by a number of reasons.
Ensure that your paper is not damp.
Ensure that you do not have toner save/eco mode turned on.
The optics may be covered in dust.
The transfer belt unit may not be lifting/locked into place correctly. Are you using genuine toner? if not try using genuine toner. Will take hundreds of copies before the quality improves.
The list is extensive that may cause this problem.

first clean the sensor in devloper unit and Replace Devloper to proper copy and check rotate toner tank or not

Hello, Glen.

Here's a link for a cleaning blade:

And, here's a link for Kyocera-Mita maintenance kits, but the specific model is not listed. You'll need to contact them at 877.813.7201 or email [email protected] to see if there is a kit for your specific model:

Hello sir;Follow the following steps to reset;
1, press "1087' "1087",
2, enter 45 then press print.
3, use zoom key to achieve a reading of "3", then press "print", "stop/clear"

you have to check the duplex unit on the machine itself.

Whoa! Flashback to 1994!
At this point you may be beyond just a simple cleaning, but try this:
Power off
Remove glass, and clean (windex or similar is fine for all of this)
Slide scanner to the right and clean mirrors, lamp, and reflectors
Then remove black lens cover (I believe 2 screws on front and 2 on back) - A magnetic screwdriver is very helpful.
Clean rear mirrors, and front and back of lens unit
There is another filter glass that should be cleaned, but it is inside the machine and the drum unit has to be removed, etc, etc, to get at it
If optics are your only problem then you should see a nice improvement in quality; However I'll be surprised if your solid 'blacks" are nice and sharp. By now I'm sure the developer is shot, and likely the drum, and blade have seen better days. Anyway, hope this helps you get a little more life out of it.
