Toner Smear If toner smears appear on the leading edge (as is passes through the printer) of the paper: • Toner may be loose inside the printer's paper path. Clean the printer by following the instructions in "Periodic - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 181
, preferably at the same location or under the same environmental conditions as the printer. 4. Use the toner management features discussed on page 6-7. The D640 printer supports several features that maximize toner usage. 5. Monitor and, if possible, manage print job sizes. Single-page print jobs - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 182
This is a standard value used by the printer industry, which is based on the assumption that the "typical" A4 or letter-size business letter is 4% covered by black area. The D640 offers a number of features that, with some trade-offs, can extend toner yield. Density The density value is factory set - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 183
. The remaining 20 to 30% is known as waste toner because in most printers it is thrown away. In a printer that uses a toner cartridge, the waste toner is never seen because it is moved to a waste area inside the print cartridge. The D640 printer is unique in the industry, providing the choice of - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 184
mixture with every rotation of the drum. The drum is often rotating even when the printer is not printing. Factory yield estimates for the drum and developer, listed on the data sheet and in this manual, can never be accurate because there is not a one-to-one correspondence between drum rotations - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 185
dust can cause excessive drum wear. If you this problem, contact your service representative or the paper manufacturer. Fuser The fuser yield is controlled by the number of times a letter or A4 sheet of paper passes through it. The printer maintains a counter which increments based on the size of - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 186
before you see any print quality or paper jam problems. When you get a "Toner Low" or "Developer end-life" message, it is best to add toner or developer as soon as possible. If toner runs out completely, or the developer reaches its endlife, the printer stops printing to prevent damage to the print - HP d640 | HP D640 High-Volume Printer - User Manual (Printer and Accessories), C - Page 187
Alignment This procedure includes the following tasks: • Printing alignment sheets. When you run the alignment program from the printer's hard drive, the printer produces a set of alignment pages. • Measuring alignment.
