Maintenance procedures of the hottest Ricoh ft4015

Maintenance procedure of Ricoh ft4015 copier

first, enter the steps of maintenance procedure:

type in sequence: energy saving key → 1 → 0 → 7 → pause key (the second key must be more than 3 seconds)

second, how to select the program number

1 Use the number keys to enter the required program number. At this time, the copy counter flashes and points (.) Also lit

2. Press the auto burst key, and the number flashing in the copy counter will be entered as the selected program number

III. change the value of SP mode

1 Use the number keys to enter the desired value or setting

2. Press the auto burst key, and the number displayed at the counter is input as a new value or setting and stored in the memory

3. The copier is ready to accept a new program number. Repeat or turn on/off the master switch once from the first step to leave the SP mode

IV. table of common maintenance procedures

program number: 4, forced start (idling). Function: perform forced start idling. Press the copy key to start idling, and press the pause key to stop idling. If this method is started, the copier will start idling before its fixing temperature reaches a specific value. When this mode is executed, the machine operates according to the selected paper size and magnification, while the paper feeding clutch and the total counter do not act. (usually, in order to prevent the maintenance call state related to fusing, use Sp7.

program number: 5, idling when the exposure light is off. Function: execute idling when the exposure light is off. Press the copy key to start idling, and press the pause key to stop idling. When this method is executed, the machine operates according to the selected paper size and magnification, while the paper feeding clutch and the total counter do not act. (usually, in order to reduce the load on the cleaning scraper, use Sp7.) As a result, the effectiveness of the designed experimental machine is low

program number: 6, paper jam detection is turned off. Function: copy, but the alignment and paper output sensors, as well as the sorter paper sensor do not detect paper jam. Press the copy key to start copying, reach the set number of sheets, or press the pause key to stop. This method is used to check whether the paper jam is caused by sensor failure. In this mode, the total counter acts

program number: 7, idling. Function: perform idling when the exposure light is on, press the copy key to start idling, and press the pause key to stop. When this mode is executed, the machine operates according to the selected paper size and magnification, while the paper feeding clutch and the total counter do not operate. Before starting, close the pressing plate to reduce the load of the cleaning scraper

program number: 8, input check

program number: 9, output check. Function: used to connect a single electrical component. Enter the required number and press the copy key to turn on the electrical components. Press the pause key to turn off the electrical components

number 10, exposure lamp + optical part cooling fan

No. 11, powder feeding motor

No. 12, Powder feeding motor (feedback)

No. 14, pager wheel drive motor

No. 15, pager wheel drive motor (bucket up)

No. 16, pager wheel drive motor (bucket down)

No. 1 the successful development of the device 7, contraposition clutch

No. 18, manual paper feeding clutch

No. 19, O) limit protection: it has two-level limit protection of program control and machinery; Tray feed clutch

number 21, interrupt wheel clutch

number 23, total counter

program number 10, scanning overhead operation. Press the copy key to idle, and press the pause key to stop

program number 11, all indications are on

program No. 48, light intensity adjustment. 110v-180v (220V machine), preset 140V

program No. 49, fusing temperature adjustment. 165 degrees to 175 degrees (220V machine), preset 190 degrees

IV. error code:

note: (1) e code is displayed on the copy counter. "E" and "code number" are displayed in turns

(2) clear the reported fault status, please disconnect and connect the main power supply

(3) in case of E5 repair request, for safety reasons, it is not recommended to disconnect and connect. Please perform the following steps: first repair the machine and connect the main power supply; Then enter SP mode 97 (enter 97 after entering SP mode, and then press the auto exposure key); Disconnect and connect the main power supply

1. E11 - exposure error (exposure does not light) - it may be a short circuit of bidirectional thyristor, an open circuit of exposure lamp circuit, and a broken thermal fuse

2. E12 - exposure error (exposure light on timeout) - AC drive/DC power board failure, main control board failure, power board failure

3. E13/E14 - zero crossing signal error - E13 is zero crossing signal, and the interval is too long; E14 is the current cycle error. According to experience, this signal is unlikely to have an internal fault. The possible reason is that the 220V mains supply is unstable. There are two ways to eliminate it: first, turn off the power switch and turn it on again; Second, turn off the power, unplug the power plug, and turn it on again after an interval of 1 hour or more. It may need to be repeated several times. Repeat the second method several times without solving it. The possible reason is that the 220V mains power quality is too poor, or it is an internal fault

4. E21 - scan rack home position error 1. Within 10 seconds after the main switch is turned on, the output of the scanning frame home position sensor remains at the low level (cut-off state), or after the scanning frame returns during the copying process, its output remains at the low level (cut-off state)

5. E22 - scanning frame home position error 2. The output of the scanner home position sensor remains at a high level (on state) within 4 seconds after the general start is turned on, or its output remains at a high level (on state) within 0.3 seconds after the scanner is started

6. E2A - the fourth/fifth reflector home position error 1. Ten seconds after the fourth/fifth reflector motor is driven, the output of the fourth/fifth reflector home position sensor remains low

7. E2b - the fourth/fifth reflector home position error 2. 10 seconds after the fourth/fifth reflector motor is driven, the output of the fourth/fifth formlabs reflector home position sensor remains at a high level

8. E28 - lens home position error 1. 10 seconds after the device returns to the home position, the output of the lens home position sensor remains at the low level (cut-off state)

9 E29 - lens home position error 2. 10 seconds after the device leaves the home position, the output of the lens home position sensor remains high and flat (on state)

10 E40 - error in thermistor of optical part

11. E42 - high voltage leakage. The high-voltage power board detects leakage and sends leakage signals to the main control board for more than 1 second

12. E52 - fusing error 1. The thermistor detects that the temperature does not reach 100 ℃ within 24 seconds (NA) or 35 seconds (EU) after the main switch is turned on. In order to clear this fault state, refer to note 3

13. E53 - fusing error 2. The thermistor detected that the temperature exceeded 255 degrees. To clear this fault state, refer to note 3

14. E54 - fusing error 3. After the main motor is disconnected, the fusing lamp is continuously on for timeout. To clear this fault state, refer to note 3

15. E55 - fusing error 4. The temperature value of thermistor does not change for a long time or exceeds 20 degrees per second
