Maintenance mode -Pressing respectively w/in 2 sec., function/set, *2864 button -Holding the function/set or menu/set button before turning the machine on. Without numeric keypad: menu, monostart, 4 times arrow up Models with resistive touch panel: 1. hold down the home key over 5 sec. on standby lcd status 2. hold down the button square area 2 sec. 3. press *2864 4. enter the maintenance mode

Service mode 01---Factory default/ reset 91---Factory reset/ except telephone storage 09---test print/ quality check 76---purge operation/ cleaning: (use in bad print) 0---head replacement 1---single purge 2---normal purge 3---power purge 4---initial init Note: 0 & 4 is very consumeable in ink (4 mins) Use power purge instead 13---operational check of keypad 32---sensor operational check: DF---document front sensor DR---doc. Rear sensor CV---cover sensor CC--- cartridge sensor PI --- purge sensor RS---rear sensor Ink sensor: IK---ink detection sensor black IM-- Magenta IC--- Cyan IY--- yellow

EK---ink sensor level Black EC---cyan EM---magenta EY---yellow

55---scanner area set Use when after replacement of scanner unit or main PCB Error: AF--- alpha foxtrot When scanner not found the plain white 59---CIS type set- scanner or main PCB 59/3/1 --- auto detect 651---alignment of vertical print line Use when change of main PCB, print head, shadow printing 682580---input of head property data (head voltage) Use when change of printer head or main PCB ALRXXXXXXXX 74---country code – telephone function 77---printout of equipment log Always need for warranty check 78---calibration of touch panel 80---display of equipment log 82---equipment error code indication 99---exit

Replacing of main PCB: 1. install firmware (program) –important to do first 2. 74—country code 3. 59 4. 55 5. 682580 6. 651 7. 32 8. 09 9. 76 10. 1 11. input serial number

Replacing the head/ carriage unit 1.68 2.76 3.09 4.65

Troubleshooting -All line of ‘2’ in error code is related to ink. Ex. Error code 2f—cover is open -All line of ‘3’ in error code is related in movement of head. -dust -encoder strip – dirt -encoder disk—dirt -paperjam Error code 46 --- ink absorber full Reset purge & flushing counts 1. maintenance mode 2. enter 80 3. find the purge (equipment list) 4. type 2783 5. count is reset (back to zero)

Error 48,49,4f: 1. Head cable—reconnect 2. Carriage flat cable---reconnect 3. carriage PCB defective--- replace PCB 4. head defective --- replace head/carriage unit

Laser printer Laser -

light amplification & stimulated emission of radiation

Toner & drum—are always separate Drum --- has a long life Toner --- last approx. 1000 pages Drum--- last approx. 10,000 pages Has photo conductor

Print out equipment log (77): Laser jet without panel button Procedure: 1. hold power button. while holding, open top cover 2. take out the drum unit & check the error led is lit 3. set the drum unit & close the top cover 4. press the button twice. Check that the error led is lit 5. press the button once to start the maintenance printing How to check sensor test Same as checking 77. Except procedure no. 4. Press button (once only)

HL printer --- are all the same maintenance mode Except 110 Procedure maintenance mode: Hold ‘go’ button in HL 110 --- hold ‘go’ button, release button then press 3x

User setting: upon power on, press ‘go’ button 3x (print test) Print test --Power off --Once go button

Factory reset ---Hold ‘go’ button and press power ‘ON’ button (back side) ---release ---press ‘go’ 8 times

Sensor test: ---Open cover ---Hold ‘go’ then press power ‘ON’ button ---Press once ‘GO’ button ---Close cover ---Then press once ‘go’ button

Maintenance mode: ---open cover ---hold ‘go’ button, press power switch ---press twice ‘go’ button ---close cover ---then press once ‘go’ button
