each other is the key to troubleshooting any problem. Detailed information regarding the troubleshooting of the HP LaserJet 2100 is included in Chapter 6: Troubleshooting. The HP LaserJet 2100 printer's four major systems are as follows: • "Formatter System" (page 72) - Receives print data from the - HP 2100 | Service Manual - Page 82
System The Formatter System is responsible for the following: • Receiving and processing data from the various printer interfaces. • Monitoring control panel input and relaying printer status information (through the control panel and the I/O). • Developing and coordinating data placement and timing - HP 2100 | Service Manual - Page 83
printer to print more pages per minute. • Non-Volatile Memory (NVRAM). Stores information about the I/O and print environment configuration. The printer keeps the contents of NVRAM when the power is turned off or disconnected. (As in other HP LaserJet printers, downloaded amount of toner applied to - HP 2100 | Service Manual - Page 84
• Uses approximately 50% less toner than standard mode printing by reducing the dot density. Users can adjust EconoMode, which can also be thought of as draft mode, through software applications. The default setting is Off. EconoMode does not affect print speed or memory usage. Figure 5-4 EconoMode - HP 2100 | Service Manual - Page 85

The default is Auto. If Image Adapt is used some data may be lost. To see if - HP 2100 | Service Manual - Page 86

The printer can receive data from more than one I/O simultaneously until the appendix of the Printer Job Language Technical Reference.

Engine Control System Specifically, the Engine Control System directly controls the following subsystems contained on the Engine Controller Assembly: • Laser Scanner Control • Paper Feed Control • Microswitch Control • Motor Control • Fusing Assembly Control • Power Supply and Control C4170-90959 - HP 2100 | Service Manual - Page 88

charges to the surface of the photosensitive drum. To form a latent electrostatic image on the drum, its surface is then exposed to the laser beam. Toner on the developing cylinder changes the latent electrostatic image on the drum's surface to a visible image, and then the transfer charging roller - HP 2100 | Service Manual - Page 91
of the image formation system that wear, degrade, or are consumed are built into the replaceable toner cartridge (see figure 5-7). This eliminates the need for a service call when replacement is required. Photosensitive Drum Figure 5-8 Photosensitive Drum The photosensitive drum is the heart - HP 2100 | Service Manual - Page 92
. During printing, the drum rotates completely several times per printed page. Before forming the image for a given section of print, a cleaning blade removes toner from the previous rotation of the drum. The toner cartridge stores waste toner and prevents it from being used in later print jobs (see - HP 2100 | Service Manual - Page 93

To prevent the toner from getting dispersed during the fusing stage, this printer applies a negative DC voltage to the fusing film via the pressure roller shaft (which is merely a continuity path - HP 2100 | Service Manual - Page 96
The fusing heater comes up to fusing temperature very quickly and thus does not require any power while the printer is on STBY. This feature saves power while virtually eliminating the warm-up period (less than 10 seconds). 86 5 Functional Overview C4170-90959 - HP 2100 | Service Manual - Page 97
