When i start the machine Taskalfa 250Ci after welcome screen error code CF040 appeared on the screen, after going through the service manual reference my error code must be install new firmware when downloaded and going through Main CPU installation progress until 100% received the following(Hi-Voltage CPU Error). Please Your Advice

SOURCE: error code: 7410

Thus: Switch the printer off again and take the DKU out inclusive toners. Open the left flap and take the toner receptacle out likewise again. Directly beside the toner receptacle a small lever/switch is on the right side. Pressures these upward and solve so the drum of the printer from the version. It pulls out a piece and presses it then again in here, so that engaging is to be heard. Now again the toner receptacle, as well as DKU+Toner reinserts and starts the printer.

C3100 Scanner carriage problem

• The home position is not correct when the power is turned on or copying the document placed on the contact glass.
Poor contact of the connector terminals.
Defective scanner home position switch.
Defective engine PCB.
Defective scanner motor.
This copier may need a service adjustment. The problem could be something as simple as a switch not being in home position. Please troubleshoot accordingly. Unplug device when troubleshooting.You should also troubleshoot it by looking to see if anything is blocking or stuck causing the carriage to not go into position.

SOURCE: Hi error code: Call service 6020:0053103 Can't

according to my reading, a flashing power lights indicates a problem you can solve on your own. while a error like you typed would mean something that you cannot resolve without help. a problem like a bad controller, or a bad chip. maybe a eeprom issue.

If Call service appears, turn off the printer, disconnect the power cord, and contact your service technician
Some errors cause the alarm to sound. To stop the alarm, press [Cancel].

#### represents a mechanical error (#=0, 1, 2, ...). Call for service. The printer does not operate when this message is displayed. The total number of pages printed is also indicated, e.g. 0123456.

This woiuld mean you printed 53103 pages with that printer before the error occurred.

Good Luck
