Printer problems

[rcmoon]

Sorry if I'm posting in the wrong area. I have an HP4014N that is giving me fits, poor print quality on envelopes. I have gone in circles, on-line, trying to find someone who sells the repair service manual so I can fix the problem. Can someone please direct me to a site I can check out to see if I can find the repair manual? Thanks. Hope posting such a request is not out of line.

your Desktop (or click System from the Windows Control Panel), click Properties, and
select the Device Manager tab. Click the plus sign (+) to expand the Ports menu item
and view Properties for your Printer Port (LPT1). Verify that the port is working properly
and it is enabled, and that you have the appropriate drivers installed. USB (Universal
Serial Bus) printer cables can also come loose, and they often conflict with other
devices. Remove any USB peripherals and try again. Next, check your printer status by
right-clicking its name in the Printer window. Is it online? Is it your default printer? If
another printer (or even a printing program, such as a virtual fax printer or Adobe
Acrobat distiller) has taken over the default role, you may be printing to the wrong place
without realizing it.
