Code: n06
Display: Media skew error
Description: Media is running obliquely.
Remedy: 1. Set media again and check reappearance. If this error is caused by user's inappropriate media setting, instruct correct media setting procedure. 2. Is suction fan judged as normal when checked through "Test: Fan" of self-diagnosis function? - Check the connection of following MAIN board assembly connectors. • Suction fan relay 1 assembly: J25 • Suction fan relay 2 assembly: J26 • Suction fan relay 3 assembly: J28 • Suction fan relay 4 assembly: J29 • Replace cable of suction fan that does not operate normally. • Replace suction fan assembly. 3. Is shielding material secured at specified position? Remount it at specified position. 4. Check pressure lever operation. Apply grease (G501) to pressure cam and make adjustment.
Code: n07
Display: Remove media
Description: Displayed if lever is raised during printing or cutting media and then lowered without removing media.
Remedy: 1. Does the same message appear if turning machine OFF and turn it ON again? If the message appears, refer to the action in check item No. 2. 2. Is pressure lever detected as normal when checked through "Sen: Lever" of selfdiagnosis function? Check that LCD monitor does not display up/down as chattering when slowly raising/lowering pressure lever. 3. Check contact of lever sensor assembly. • Reconnect MAIN board assembly connector J30. • If LCD displays as chattering, sensor may be damaged. Replace lever sensor assembly. 4. Is media rear sensor assembly under media guide R connected correctly? Securely connect it to MAIN board assembly connector J42. 5. Check presence of media from "Sen: PaperRear AD" of self-diagnosis function. When "No media" is displayed even if media is set, replace media rear sensor assembly. 6. MAIN board assembly may be damaged. Replace MAIN board assembly.
Code: n08
Display: Media cut error
Description: Even though cutting operation is performed, media is not cut off.
Remedy: 1. Does media dust accumulate in cutter groove? Remove accumulated media dust along groove. 2. Is cutter cap securely installed? Reinstall cutter cap securely. 3. Check cutter sliding up/down operation. When setting cutter, lower cutter with finger and check that cutter rises to upper end only by spring force. • When it does not rise: Refer to action in check item No. 4. • When it rises: Refer to action in check item No. 5. 4. When setting cutter after removing cutter spring, does cutter lower to lower end by its own weight? • When it lowers: Cutter spring may be defective. Replace cutter spring referring to exploded views. • When it does not lower: Cutter may be defective. Replace cutter. 5. Check if solenoid goes up/down from "Life: Cutter" of self-diagnosis function. a) Goes up/down: Check the position where cutter goes down to cutter groove. • OK: Cutter has reached the end of life or be damaged. Replace cutter with new one. • NG: Adjust cutter holder position. b) Does not go up/ down: Connector may be poorly connected. Check the connection of following connectors. • CR board assembly: J206 • CR board assembly: J201, J202, J203 • MAIN board assembly: J9, J10, J11 6. CR_FFC may be broken, solenoid assembly may be defective, or each board assembly may be defective. a) Replace CR_FFC with new one. If solenoid goes up/ down, replace CR_FFC. b) Replace solenoid assembly with new one. (Check by connecting connectors directly) If solenoid goes up/ down, replace solenoid assembly. c) Replace CR board assembly. After replacement, adjust sensor reflection amount from "Sen: PaperEdge AD" of "Test: Sensor" of selfdiagnosis function. d) Replace MAIN board assembly. Before replacing MAIN board, back up parameters and recover to new MAIN board assembly. Then start operation check.
Code: n09
Display: 1. [KCMY] Ink Near End 2. [KCMY] Ink End The ink color that is/are subject to this caution is/are displayed in the [ ].
Description: 1. Ink is running short. Printing is possible. 2. Ink has run out. Any printing operation stops immediately.
Remedy: 1. Check which cartridge has no ink from "Sen: Ink NOT" of selfdiagnosis function. Remove all cartridges and lightly push the black resin lever of ink sensor assembly (K, C, M, Y) to check that the display of "Sen: Ink NOT" changes. 2. Check contact of the ink sensor assembly. Reconnect following connectors. • Connector J5(K) • Connector J6(C) • Connector J7(M) • Connector J8(Y) 3. For the ink color that is displayed as "Ink Near End" or "Ink End", switch ink sensor assembly connector with that of normally displayed ink color. • If ink color display changes after replacing connector: Ink sensor assembly is damaged. Replace ink sensor assembly. • If ink color display does not change after replacing connector: MAIN board assembly may be damaged.Replace MAIN board assembly.
Code: n10
Display: [KCMY] No Cartridge
Description: Cartridge is not installed.
Remedy: 1. Turn machine OFF. Turn it ON again and check if the same message appears. If message appears: Refer to action in check item No. 2. 2. Check presence of ink cartridge from "Sen: Ink NOT" of self-diagnosis function. Remove all cartridges and lightly push the switch of ink NOT sensor assembly (K, C, M, Y) with something with a flat tip such as ballpoint pen to check that the display of "Sen: Ink NOT" changes. 3. Check contact of ink sensor assembly connector. Reconnect following connectors. • Connector J5(K) • Connector J6(C) • Connector J7(M) • Connector J8(Y) 4. For the ink color that is displayed as "No cartridge", switch ink sensor assembly connector with that of normally displayed ink color. If ink color displayed as "No cartridge" changes after replacing connector: Ink sensor assembly is damaged. Replace ink sensor assembly. If ink color displayed as "No cartridge" does not change after replacing connector: MAIN board assembly may be damaged. Replace MAIN board assembly.
