The HP LaserJet Quick Reference Service Guide, Volume II, provides support for newer monochrome printers (see the following page for a complete list of supported printers). It has been created to help the HP LaserJet service engineer quickly troubleshoot common printer problems.
For older monochrome printers, see the HP LaserJet Quick Reference Service Guide, Volume I. It provides support for the following printers: LJ 6L, LJ 5Si Mopier, LJ 5Si, LJ 5Si MX, LJ 5L, LJ 6P, LJ 6MP, LJ 5P, LJ 5MP, LJ 5, LJ 5M, LJ 5N, LJ 4V, LJ 4MV, LJ 4P, LJ 4MP, LJ 4L, LJ 4ML, LJ 4+, LJ 4M+, LJ4, LJ 4M, LJ 4Si, LJ 4Si MX, LJ IIISi, LJ IIIP, LJ IIP+, LJ IIP, LJ IIID, LJ III, LJ IID, LJ II, LJ 2686D, LJ 2686A. While the quick reference guides are intended to provide all the information the service engineer will need for on-site repair of HP products, they are not intended to replace the service manual for any HP LaserJet product. For detailed information about the HP LaserJet products described in this guide, see the user guide or service manual for that product. Service manuals for HP LaserJet products are available from Hewlett-Packard. The phone number for the Service Parts Order Desk is:

The AC line voltage for the LaserJet 5000 printer is applied through the main switch (SW 101) and supplied to the low-voltage power supply circuit through the fuse (FU1). The low-voltage power supply divides the AC voltage to +24 VDC, +5 VDC and +3.4 VDC and supplies them to the DC controller PCA. This circuit generates a zero-cross signal (ZEROX) and supplies it to the DC controller PCA. DC power is supplied as follows: +3.4 VDC · ICs on the DC controller PCA and the BD PCA

Protection Systems
Problems on the load side, such as short-circuits, can cause an excessive flow of current from the DC power supplies or can generate abnormal voltage. When this happens, the excess-current and excessvoltage protection systems automatically shut off output voltage to protect the power supplies. If the protection systems are activated and the power supply circuit does not output DC voltage, turn the printer off, correct the problem in the faulty load, and then turn the printer on again.
