Solution to Lenovo lj2500 activation processor error

A Lenovo lj2500 laser printer in my office suddenly experienced a power failure when printing files. After a call, the printer switch was turned on, the "toner cartridges", "Ready lights", "warning lights", and "Data lights" on the printer control panel are constantly flashing, And the toner cartridges cannot be preheated after normal boot. According to the fault symptom reference provided in the printer user manual, this error indicates that the printer processor encountered an error during operation. As described in the Manual, I first turn off the printer power supply and wait for a moment before turning on the power switch. The system displays "Printer error, the system cannot specify the device ".

Troubleshooting: due to the distance from Lenovo's service station, I decided to solve the fault myself. Generally, printer processors are not burned out due to sudden power outages, most of which are soft faults. Therefore, I decided to give the printer a try to print the test page: First close the printer, and then press the control panel button on the printer to turn on the printer power, at this time, the four indicators of toner cartridges, readiness, warning, and data blinks a few times, and the remaining toner cartridges are on. Release the control panel button and press the button again. The printer does not print the test page, but at this time, the toner cartridge indicator is off, and the familiar ready indicator is on-this is a normal indication after the printer is started. I quickly turn off the printer power, and then re-open, you can hear the sound of the toner cartridge when pushing, re-call the document printing, print back to normal.
