CANON printer LBP5000 type cyan plus powder, after one third level throughout the test page prints out there on the right side of the green color, add powder completely normal - before Shenzhen drum manufacturers
phenomenon description: CANON printer cyan LBP5000 homemade drum unit type after add powder throughout the test page prints out there on the right side of a third wide cyan, add powder before completely normal.
failure analysis: after add powder appear problem, that there is an error in the add powder, from the point of fault sample, should be developed series of development on the right side of the collar is not installed. CANON printer LBP5000 type USES is by leaps and bounds development, do not contact directly with developing roller, photosensitive drum but by superposition of ac and dc voltage, carbon powder in developing jumping between roller and the photosensitive drum, developing roller set is to determine the development of the distance between the roller and the photosensitive drum. If the drum and developing series of contact, whether or not the electrostatic latent image area, carbon powder will be sucked into the drum, the above phenomenon. So, developing bushing wear loss and can cause printing image is not normal.
processing methods: re-install lose enhancement on collar (CANON printer supplies LBP5000 type regeneration> for reference.
CANON printer LBP5000 type magenta plus powder after print out, other colors
normal phenomenon description: CANON printer LBP5000 type magenta plus powder after print out, other colors is normal.
failure analysis: this kind of situation is due to the spring not hanging on both sides of the compact, developing roller and the distance between the photosensitive drum is too large, carbon powder on the photosensitive drum, formation of image. ( CANON type LBP5000 printer made by leaps and bounds development. ) So, lack of color printing.
the printer engine test page
in the similar HP1600/2600 series color laser printer panel, or CANON LBP Type 5000 printer didn't have a panel, and without condition online print proof, can through the printer engine test page, judge whether the printer engine parts work normally. Below is the print engine test page method.
open the printer power switch, when the printer is in standby mode, as shown in figure 5 - 53, figure 5 - Print engine test page 54 method.
