Copystar CS-1815 C4000 Error Code – Polygon Motor

 

Diagnostic aids and troubleshooting for the Copystar CS-1815  C4000 Error

The CS-1815 C4000 Error is related to the laser scanner assembly. If the laser scanner assembly doesn’t reach it’s operating speed within 15 seconds of start up then the machine throws this error code. In this article I’d like to give a few troubleshooting tips. Sometimes the motor just stops and locks up. Other times, when the motor bushings get dry, the machine will make a loud screeching noise when the motor starts up. If you hear the loud screeching noise followed by the C4000 error then you know the polygon motor is failing to get up to speed to to a friction problem.

Troubleshooting tips for the CS-1815 C4000 Error

1. Turn the machine off then back on. Sometimes these errors are a temporary fault and can be solved by just turning the machine off then on.

2. Reseat the connectors from the laser scanner assembly.

Warning : This next step is a last resort. Sometimes this works and other times it doesn’t. The laser scanner assembly is expensive so it might be worth the effort if your only other option is to purchase a new machine. If you feel this repair step is beyond your expertise then proceed to step 4.

3. Over time dirty and debris can get into the laser scanner motor or the lubrication gets dry. When this happens the motor doesn’t get up to speed. These motors are free floating and it doesn’t take much to slow them down. Remove the laser scanner assembly cover and remove the motor from it’s housing. Use alcohol to clean the motor shaft and use a light lubricant on the shaft and a small drop in the motor bushing.

Note: The polygon motor has several mirrors on it. Any scratch or smudge from greasy fingers can result in poor print quality. Be extremely careful when cleaning and if you must clean the mirrors use a dry Q-tip and gently wipe. If you see it start to scratch the surface of the mirrors stop immediately.

4. Replace the Laser Scanner Assembly.

5. Replace the Engine Control Board.

Replacement Options

Like I mentioned before, the laser scanner assemblies for these machine can be expensive. If you decide to replace the machine I have provided some Kyocera models and my personal favorites, Brother machines, that I feel are the equivalent or better than the Copystar CS-1815.
