Introduction This chapter presents an overview of the relationships between major components in the HP Color LaserJet 2500 series printer, and includes a detailed discussion of the image-formation system. The following systems are discussed: engine control system laser/scanner system pickup - HP 2500 | Service Manual - Page 63
Engine control system The engine control system coordinates all printer functions. It drives the laser/scanner system, the image formation system, and the pickup and feed system.

Laser/scanner system The laser/scanner system receives video signals from the dc controller, and then it converts the signals into latent images on the photosensitive drum. The dc controller controls the laser/ scanner. Figure 14. Laser/scanner system EN 4 Theory of operation 65 - HP 2500 | Service Manual - Page 68
Pickup and feed system The pickup and feed system consists of several types of feed rollers and sensors. The dc controller drives the paper and feed system by controlling two motors, two clutches, and the solenoid. Two photo-interrupters (PS1 and PS711) detect media as it passes.

The image formation system, which forms a toner image on media, consists of several interdependent systems: electrostatic latent-image-formation system developing system transfer block fuser ITB cleaning block imaging drum (with ITB) photosensitive drum Figure 23. Image formation - HP 2500 | Service Manual - Page 75
, optics, and electrophotographics to provide a printed page. Each process functions independently and must be coordinated with the other printer processes. Image formation consists of the following five processes: 1 Latent-image formation 2 Developing 3 Image transfer 4 Fusing 5 Transfer-belt - HP 2500 | Service Manual - Page 76
25. Step 1: primary charging Step 2: laser-beam exposure The laser beam scans the photosensitive drum to neutralize negative charges on parts of the drum. An electrostatic latent image is formed on the drum where negative charges were neutralized. Figure 26. Step 2: laser-beam exposure 74 Theory - HP 2500 | Service Manual - Page 77
friction from the developing cylinder and the blade. When the negatively charged toner comes in contact with the drum, the toner adheres to the electrostatic latent image.

This prevents toner from falling off of the transfer belt, scattering in the printer. - HP 2500 | Service Manual - Page 81
(transfer belt cleaning roller) The transfer belt cleaning roller, to which a dc positive bias is applied, imparts a positive charge to the residual toner on the transfer belt. This positive charge is stronger than the positive charge applied in step 8, so the earlier charge now behaves like - HP 2500 | Service Manual - Page 82
: transfer belt cleaning A dc positive bias is applied to the transfer belt to produce a difference in potential between the belt and the photosensitive drum. This causes the transfer of the residual toner to the drum. Figure 35. Step 10: transfer belt cleaning 80 Theory of operation C9706-90926 - HP 2500 | Service Manual - Page 83
Step 11: drum cleaning The cleaning blade scrapes the residual toner off of the photosensitive drum, where the waste toner screws collect and deposit the toner into the waste toner case. Figure 36. Step 11: drum cleaning EN 4 Theory of operation 81 - HP 2500 | Service Manual - Page 84
Print cartridge The printer has four print cartridges: yellow, magenta, cyan, and black. Each print cartridge contains a developing cylinder, toner-feed roller, and stirrer. The developer motor rotates these parts, so that each print cartridge can use toner to form a visible image on the drum. The - HP 2500 | Service Manual - Page 85
