If you're setting up the printer or changing the toner or ink cartridge for the first time, double-check the instructions to make sure that you installed the cartridge correctly and, for new printers, that you have removed all the pieces of cardboard or plastic packing material.
Check to see whether paper is feeding from the paper tray. If it's not leaving the tray at all, try feeding a page manually (if that's an option) or using a different paper tray. Sometimes a problem with the tray can be traced to a broken spring or a piece of plastic.
If paper is feeding from the tray but jamming in the printer, examine where the jam is occurring and then inspect the printer carefully to see if you can find what is causing the problem. A piece of paper, for instance, might be blocking the paper path.
If paper is feeding through the printer but coming out blank, check to see whether the printer is out of toner or ink. A defective toner or ink cartridge could be the problem.

Missing or incorrect color
You have changed the color settings manually. Return the color setting to Automatic. • Windows: On the Color tab of the printer driver, click Automatic. • Mac OS: In the Print dialog box, select the HP ColorSmart or HP Color Quality pop-up menu and then select the Manual option.
Your print media does not meet the specifications for this printer. For example, you are using coated, glossy, or photo paper. Use a different paper, such as a high-quality paper designed for laser printers. See the user guide for information about print-media specifications.
You are operating the printer in excessively humid or dry conditions. Verify that the printer environment is within humidity specifications. A print cartridge might be low on toner. Check the printer control panel, print a Supplies Status page, or view the embedded Web server (HP color LaserJet 2500 series printers only) to see supplies status. (If you are using a non-HP cartridge, none of these sources will provide information about a low or empty print cartridge.) If a cartridge is low on toner, replace the print cartridge.
Clean the sensors and perform a calibration.
The HP Color LaserJet 1500 Series Toolbox is not supported for the Macintosh operating systems. 1 Make sure that the printer is turned on and in the Ready state. 2 Open the Toolbox. 3 On the Troubleshooting tab, click Cleaning Page and click Print. A page with a pattern prints from the printer. 4 At the printer, remove any media from tray 1 (multipurpose tray). 5 Remove the page that printed and load it face-down into tray 1 6 At the computer, click Clean.
Note For even better results, repeat this procedure several times.
The printer automatically performs a calibration when the imaging drum or a print cartridge is changed, and at set intervals that are determined by the total number of pages the printer has printed. For the HP Color LaserJet 2500 series printers, you can change the interval at which the printer performs automatic calibrations by using the embedded Web server.
To calibrate the printer manually Turn the printer off, wait one minute, and then turn the printer on again.
To calibrate the printer from the Toolbox The following procedure must be performed from the HP Color LaserJet 1500 Series Toolbox or the HP Color LaserJet 2500 Series Toolbox, which are only supported for Windows 98, NT 4.0 (HP Color LaserJet 2500 series printers with parallel connections only), Me, 2000, and XP.
Note The HP Color LaserJet 1500 Series Toolbox is not supported for the Macintosh operatingsystems. 1 Open the Toolbox in one of these ways: • On the desktop, double-click the HP Color LaserJet 1500 Series Toolbox or HP Color LaserJet 2500 Series Toolbox icon. • On the Start menu, point to Programs, point to HP Color LaserJet 1500 or HP Color LaserJet 2500, and select the HP Color LaserJet 1500 Series Toolbox or the HP Color LaserJet 2500 Series Toolbox. 2 On the Troubleshooting tab, click Diagnostic Tools (on the left side of the screen). 3 Click Calibrate Now.
Hope this helps!

Did it ever work?
You are using the Post Script drivers, right?
Power down the printer from the back. Disconnect the power cord. Plug it back in and power it up.
Check the graphic language setting of the printer(look at the User Guide)
Resend the file.
Upgrade the firmware to the latest version (www.hp.com/#support)

Testimonial: "thanks, We actually had someone from another governmnet department that uses the exact same printer. and once we connected he gave the exact advice. "
SOURCE: I'm getting 47:01 error on
It doesn't need cleaning, it needs to be replaced. It's located on the right side of the printer behind the ride side cover. If you haven't been trained you arn't going to replace the motor. After it gets replaced the printer has to be re-calibrated. If it is still under warranty, use it. Otherwise, get a designjet tech to work on it.
