The following cycle is a generic guide for maintenance. An example table is used to receive and transmit 50 files per day on average. Environmental conditions and actual use change these factors. The following cycle is for information purposes only. The pbx 2,500 page picks up the 60 000-page page of the 60 000-page page delivery of the 60 000-page imager 60 000-page drive 4-2 the print mass serial number image abnormality type black image 75. 4 mm white point black point 2 charge point 37. 7 mm black point 3 provides 4 辊 26. 8 mm dark zone black side of the 31. 6 mm level contamination/ transmission 5 conveyance 47. 1 mm black point 57. 1 mm failure 6 white point 7 plating 56. 5 mm black side pollution 4-3 dcu (diagnostic) controls 4-3-1 dcu setting for printer failure. Before using dcu, open and remove the front exit cap of the printer, and remove the bottom cap from the left. Connects the dcu line (10 to 4 needles) to the cn9 (4 needles) on the control board. The 4-3-2 status code connects the dcu to the printer and then turns on the power. Dcu displays the state code with a light diode in sector 7. There are two state codes: normal and wrong. Status code indicates the status of the printer. Normal state codes, which represent the paper position in the paper channel when the printer is printed or preheated. Printer 61 pre-heat preheat when the printer opens, closes the cover or activates from hibernation mode. Preparation (paper printers are printable. Tests the type of paper after printing a page. 00 ~05: legal, 01:letter, 02:a4,03:exec, 04:b5,05:folio shows 20 printing starts when the engine controller receives the " print " command from the video controller. 30 in to the sensor and this code indicates that the paper is going through the sensor. 40 goes to the sensor and breaks this code means the paper has passed through the sensor. This code indicates that the paper has passed through the export sensor. The code 69 hibernation mode indicates that the printer's accelerator is closed, with the least electricity consumption. If the printer stops printing because of any malfunction, the dcu displays the wrong state code. 60,62, speculator error. These codes indicate that the speculator is wrong. Heating lamps, heat-sensitive electrical resisters, heat 68 power switches on or short circuits for electro-heat regulators. Check for " cryogenic error " when printer printing. 60: spectrometer open error 62: low heat error 68: excessive heat error
