CHAPTER 5 SERVICE SUPPORT SOFTWARE 1. CONTROL PANEL Various modes can be used if the power switch is set to ON while the [Go] button is held. There are two types of modes: User Mode and Service Mode. Three types of LED display are used to indicate that present setting. • Toner/Drum/Error LEDs are lighted at the same time to show that transfer to thespecified mode is completed. • Ready LED is lighted to show that the [Go] button is held when the mode or function is selected.
1.1 List of service support functions Front cover Close Open Press the [Go] button Press the [Go] button or SW supporter when or SW supporter when sifting the mode selecting the function Once Once Twice Function Refer to: Once 1) Test Sample Page 5-4 Twice 2) Print Fonts 5-4 Three times 3) USB 2.
1.2 User Mode Basically, user mode should be accessed by service personnel only. However, if there is demand, you can disclose to end users. (1) Check that the front cover is closed. (2) Turn ON the power switch while holding down the [Go] button. Check that Toner/Drum/Error LEDs are lighted. (3) Release the [Go] button and check that all LEDs are out. (4) See accompanying table, press the [Go] button again depending on the necessary number of times. Each mode starts 2 seconds.
Functions of each “User Mode”. 1) Test Sample Page The machine prints a demo page. The machine returns to the ready status after printing. 2) Print Fonts It is an effective function only for HL-2150N/2170W. The machine prints a list of the internal fonts. The machine returns to the ready status after printing. 3) USB 2.0 FULL Serial Number Return Value Setting When the OS used the USB 2.
1.3 Service Mode The service mode is exclusively designed for the purpose of checks, settings and adjustments, and this function should be accessed by service personnel only. You can perform a print test and display the log information. (1) Check that the front cover is open. (2) Turn ON the power switch while holding down the SW supporter. Check that Toner/ Drum/Error LEDs are lighted. (3) Release the SW supporter and check that all LEDs are off.
Press the SW supporter twice Press the SW supporter again depending on the necessary number of times after check that Toner/Drum/Error LEDs are lighted. Press the SW supporter Mode Once 16) Printing for Maintenance * Start printing when close the front cover. Twice 17) Printer Settings * Start printing when close the front cover. Three times 18) Sleep Mode Indication (OFF/Dimmed) Four times 19) Sleep Mode Setting (ON/OFF) * Check that all LEDs are lighted for one second.
Functions of each “Service Mode”. 9) Factory Inspection Mode This mode checks the operation of each sensor, solenoid, fan, scanner motor and main motor to check the point with the malfunction, when repair the machine. • This mode is included in the machine software. • The machine goes into the inspection mode by a special operation when the power is turned on.
• Check that the Toner LED goes out. Verify that the Ready LED is lit when pressing the [Go] button while the front cover is closed. (When you press the [Go] button while the front cover is closed, the Toner LED goes out.) It remains off while the [Go] button is being pressed. • Check the fan operation. Close the front cover and verify the fan operation. (Verify full- speed and half-speed rotations, and halt.) The fan must repeat the following operations whenever the cover sensor is pressed.
15) Paper Size Setting (A4/Letter) You can select the paper size setting (A4/Letter) of the machine body. Whenever you switch this mode, the setting is changed over from the present one to other. You can verify the setting change by LEDs when releasing the SW supporter. When the Toner and Drum LEDs light for 1 second, the paper size is set to Letter. When launched without LED lighting, the paper size is set to A4.
Display terms is as follows. Series name Model name of machine Serial Number Serial number of machine Device Status Page Count, Drum Count, Average Coverage The maximum count for each item is 1 million times. Drum Information Estimated Pages Remaining, % of Life Remaining. Total Pages Printed* Previously Used Toner, Current Toner. Total Pages Printed Total Pages Printed (Tray 1, Manual Feed). The maximum count for each item is 1 million times.
17) Printer Settings If you want to know the drum unit life or the number of printed pages, you should print out the Printer Settings. The “Printer Settings” is configured with one page for HL-2140, three pages for HL-2150N and four pages for HL-2170W (The wired LAN and wireless LAN is set to ON). All pages have following terms in common, Title, Model name, Serial number. The setting indication is the same as the LCD setting information, supporting the following 18 languages.
■ Page 1 This page includes various setting information of the machine. • Printer information In the following order - Controller Version (CONT.ROM VERSION) - Net work Version (NET ROM VERSION) But, HL-2140 is not indicated - RAM SIZE (Mbyte) • Printer settings information Each term is indicated when if fulfills the condition, and HL-2140 is indicated the maintenance information to the Page 1. ■ Page 2 This page includes the printer information and the maintenance information in the following order.
CAUTION: • The drum unit life is shown by the band graph at the center of Printer Settings. Drum Unit Life How to Read the Drum Unit Life - It initially indicates 100% and gradually decreases. - It indicates 0% when the Drum LED is blinking. - It stays at 0% even if further printing is done. How to calculate the drum unit life The drum unit life is based on the “drum counter” or the “number of drum rotations”. The drum counter is based on the total printed pages on the drum unit.
(2) Counter information, history information The counter and history information related to the following term are included. When it reaches the maximum count, each term is no longer counted. Page Count The total number of printed pages . The maximum count is 1 million pages. Total Pages Printed The number of times that each of the Tray1 and Manual Feed is used. The maximum count for each item is 1 million times. The information above is not cleared when replacing the PF kit.
■ Page 3, 4 These pages include various network settings information of the machine.
2. OTHER SERVICE FUNCTIONS 2.1 User Maintenance Mode This section describes what the end user should do when replacing the consumable parts. ■ Resetting the drum counter The printed image may deteriorate when using the drum unit to a certain degree.
■ Initializing the developing bias When replacing the toner cartridge with a new one, the new toner sensor detects that the toner cartridge is replaced, and the developing bias is initialized automatically. Therefore, the end user is not necessary to initialize the developing bias. If replacing the toner cartridge which contains enough toner with a used one, the new toner sensor cannot detect that the toner cartridge is replaced so that the developing bias is not initialized.
