Solution

 

 

Computer software

Check that your computer is working correctly by printing from a

problem.

program you know works, or by printing a plain text file to see if the

 

problem is with your program or with your driver. (For example,

 

C:\dir>LPTn where n is the number of the computer port the MFP is

 

connected to, for example LPT1.) To print the page, you might have to

 

send a form feed command from your computer.

 

 

Control-panel settings, such as RESOLUTION or ORIENTATION, do not work or are ignored.

Software commands override control-panel settings (see Using control panel menus for information about how your program works with control panel settings).

Data from a previous print job is still in the MFP buffer.

●Make sure that you are using the correct driver.

●A complex print job might still be processing.

●Make sure the MFP is not paused. Make sure the control panel reads PROCESSING JOB. If the MFP is paused, press START to resume printing.

●Pull out the print cartridge and check for jammed media. Reseat the print cartridge.

●Open Trays 2 and 3. Make sure that the appropriate media is inserted (see Media specifications). Close the trays.

Data is missing, but there are no MFP messages.

●Check your software application to be sure the print file contains no errors.

●Check your cable to make sure it is securely connected to both the MFP and the computer.

●Your parallel cable might be defective. Use a high-quality cable. (See Parts and accessories or go to www.hp.com/support/ lj9040mfp or www.hp.com/support/lj9050mfp for an HP cable part number.)

●Check your network connection.

Data light is flashing, but nothing prints.

●Make sure that you are using the correct driver.

●A complex print job might still be processing.

●Make sure the MFP is not paused. Make sure the control panel reads PROCESSING JOB.

●Pull out the print cartridge and check for jammed media. Reseat the print cartridge.

●Open Trays 2 and 3. Make sure that the appropriate media is loaded (see Media specifications). Close the trays.

Driver might not be set up to print on both sides of the paper.

Make sure that the option to print on both sides of the paper is properly configured in the driver.

(see Media specifications).

 

 

First page takes much longer to print than following pages.

●Make sure that the MFP displays READY.

●Set the Sleep feature for a longer time period (See Configuration page). If a page takes longer to print due to complex formatting commands, changing the Sleep setting might not improve print speed. You might want to simplify the page.
