On customer complaints HP CP1215, 1515.1518.CM1312, HP CP2020,2025,2025DN, CM2320 will be reported C, M, Y, K and other different colors of the cartridge loading lock is not removed, the English prompt is: remove shipping lock from black / color cartridge print chip does not work, the printer can not print the problem, in fact, have nothing to do with the quality of the chip! For example: HP540 and HP530 products, shipping lock error, resulting in the chip can not print the case, the real reason is:

First: may be the toner cartridge end of the gear installed in place caused by the error!
When the drum end of the gear lever to promote the movement is not smooth, or push fixed, the cartridge into the printer, the plastic can not push the push rod, the printer machine will be an error! Misjudgment did not disassemble seal! He put this wrong message through the chip's report!
Approach: Disassemble the cartridge, reinstall the cartridge gear side, to keep the gear push rod to promote smooth, easy!
Special Note: If there is more than the above phenomena, it is necessary to determine whether it is possible and some new mold factory white push rod size failed, will also cause such an error, at this time to replace the white putter!

Second: check the surface of the cf230x has no uniform toner coverage This is one of the main reasons
Toner cartridges developing stick surface with a layer of even the surface of the toner, toner-free developer surface will cause the printer error!
Approach: Rotate the developer stick by hand, so that the surface of the developer stick with a uniform toner.
Special Note: This series of toner cartridges smaller capacity, can not add too much powder, too much powder added, will increase the rotation of the powder bar in the powder storehouse rotation resistance, resulting in powder stick damage!

Third: check the drum chip installation thickness, whether the card in place! Whether the installation direction is accurate, whether the chip copper and the machine contact angle bad!
Drum chip installation direction error, or the chip back of the fixed double-sided adhesive too much, will cause the counting chip installation is not in place, the printer does not detect and reported this wrong!
Approach: The gap toward the inside of the chip installed, while detecting the printer chip contact spring contact angle deviation occurs, put him straight!
Special Note: Some chips have been identified by the printer and passed, it will not be reported Transport Lock wrong!
