1 7 Solve problemsTo use the information in this chapter, you should have a basic understanding of the HP laserjet printingprocess. Explanations of each mechanical assembly, the product systems, and the basic theory ofoperation are contained in Theory of operation on page 79. Do not perform any of these troubleshootingprocesses unless you understand the function of each product : Unless otherwise noted, all illustrations depicting the HP laserjet P2050 series Printers arealso valid for the HP laserjet p2030 series Printers.

If theproduct does not pass a step, follow the corresponding troubleshooting suggestions. If a step resolvesthe problem , you can stop without performing the other steps on the sure the product Ready light is on. If no lights are on, complete these the power-cable that the power switch is sure that the line voltage is correct for the product power configuration.

3 (See the labelthat is on the back of the product for voltage requirements.) If you are using a power strip andits voltage is not within specifications, plug the product directly into the wall. If it is alreadyplugged into the wall, try a different that connectors J2 and J7 on the formatter PCA are seated. See Figure 7-3 Components on the left side of the product on page an engine test. If the test is successful, replace the control panel and then theformatter PCA. See Top-cover assembly on page 124, Formatter PCA; HP laserjet p2030 series on page 130, or Formatter PCA; HP laserjet P2050 series on page the the cable connection between the product and the computer or network port.

4 Makesure that the connection is sure that the cable itself is not faulty by using a different cable, if the network connection. See Solve network problems on page to see if any messages appear on the control-panel display. If any error messages appear,see Interpret control-panel messages (HP laserjet P2050 series Printers only) on page to see if any control-panel lights are lit. See Status-light patterns (HP laserjet p2030 SeriesPrinters only) on page sure that the print media that you are using meets a configuration page. See Print the information pages on page the pages do not print, check that at least one tray contains print the page jams in the product, see Clear jams on page the configuration page prints, check the following items.

5 If the page prints correctly, then the product hardware is working. The problem is with thecomputer that you are using, with the printer driver, or with the one of the following options:Windows: Click Start, click Settings, and then click Printers, or Printers and Faxes. Double-click the name of the Chapter 7 Solve problemsENWW-or-Mac OS X: Open Print Center or printer Setup Utility, and double-click the line for the that you have installed the printer driver for this product. Check the program to make surethat you are using the printer driver for this a short document from a different program that has worked in the past.

6 If this solution works,then the problem is with the program that you are using. If this solution does not work (the documentdoes not print), complete these printing the job from another computer that has the product software you connected the product to the network, connect the product directly to a computer witha USB cable. Redirect the product to the correct port, or reinstall the software, selecting thenew connection type that you are that affect product performanceSeveral factors affect the time it takes to print a job: Maximum product speed, measured in pages per minute (ppm) The use of special paper (such as transparencies, heavy paper, and custom-size paper) Product processing and download time The complexity and size of graphics The speed of the computer you are using The USB connection The product I/O configuration The amount of memory installed in the product The network operating system and configuration (if applicable)NOTE.

7 Although additional memory can improve how the product handles complex graphics andimprove download times, it will not increase maximum product speed (ppm).ENWWS olve general problems 187 Basic problem solvingTable 7-1 Basic problem solvingProblemCauseSolutionWhen the product is connected to acorrectly grounded power source, theLEDs on the control panel do notilluminate and the main motor does product does not turn power to the that the power switch isturned that the power cable iscorrectly plugged into the outlet andthe that the power outlet has thecorrect power inlet/switch cable assembly the power inlet/switch cableassembly.
