载体如果出现问题,一般是要及时更换的。C500需要及时更换的耗材只有两个:载体和臭氧过滤层(除非不在乎健康)。 |

有一次把8050的载体DV501K加到C500里面(应该是DV510K),忘了做L检测,打印过程中就是不加碳粉,发白了也不加。也是一位师傅来加的,害得我忙乎了半天,电话里说: 1)说是载体加得太多,我掏出几勺。 2)初始碳粉不够,我手工加碳粉,印了几百张,还是发白。 把这位师傅的载体袋子从垃圾桶捡出来,一看是DV501K,气得我大骂。这位师傅回来,换上了DV510K,L检测后,一切正常! 总之,机器用长时间了,自己就慢慢的会修了,不过修之前要想想,问几个为什么。 |

cause: Dmax control /k resulted in an abnormality estimated parts : printer control board, developing unit ,gamma sensor active solutions use the flow chart Subject: SC29-07, SC29-08, SC29-09, SC29-10 error codes. Description: SC29-07, SC29-08, SC29-09, SC29-10 error codes. Solution: PROBABLE CAUSES: 2. Setup adjustment performed incorrectly. Recall the process adjustment standard data and perform the gamma auto adjustment after insuring that the drum cartridges and charge coronas are properly seated. To recall the process adjustment standard data, perform the following: a. Power on the copier while pressing 3 and 6 on the control panel. b. Select PROCESS ADJUSTMENT followed by RECALL STANDARD DATA. c. Select YES and then perform the normal setup. 3. The transfer roller behind the transfer belt has dislodged from the power block assembly. Check the corresponding transfer roller (p/n 65和谐26120R) for the corresponding color code that might have dislodged from the power block assemblies (p/n 65和谐-2810, p/n 65和谐-2820). Also, check the continuity of the blocks. 4. Excessive yellow due to high yellow charge grid (shown on Adjustment List as Grid Y 1/1(V) setting = 1015), due to failed HV-1. Replace HV-1 (p/n 65和谐84010). 5. Bias contact on the rear of the developing unit is malformed resulting in insufficient contact with the bias spring located on inside of the machine on the rear side. Reform the bias contact so that it contacts the spring on the inside of the machine. 6. Faulty Gamma Sensor. Replace the Sensor Unit Assembly (Image Color Registration Unit) (p/n 65和谐-2950). 7. Worn developer. Replace developer. 8. The toner spew mylar located just below the magnet roller of the developing unit is misaligned resulting in the developer on the magnet roller not developing correctly on the sleeve resulting in PS11 (Gamma sensor) not reading the patch correctly. Remove the developing unit, then loosen the 3 screws located on the toner spew mylar guide allowing the black plastic plate which the mylar is mounted on to move down. Retighten the 3 screws and reinstall the developing unit. WARNING: Do not touch the screws for the doc blade because it is factory set. |
