Archive of about 174 KB containing the Canon Service Tool for the PIXMA MP287 multifunction printer. Technicians use it on Windows to clear the waste ink absorber counter behind errors like 5B00 or P07, run EEPROM operations and print nozzle check patterns. The printer must first be placed into service mode with the proper button sequence, and the tool then communicates over USB. Some functions vary by tool version, so check that the MP287 responds correctly, and service the ink absorbers before clearing the counter.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @BiosSchematicBoardviewNoLimit. Enginerys does not host this file.
