Scanjet 4p fails self-test

Posted on 2000-03-21
Last Modified: 2013-12-15
I've bought a used HP Scanjet 4p (type C1130 A) last week.
My SCSI Card (Tekram DC-390U) correctly recognizes the scanner, and during the next Win98-boot the 'new Hardware' - Window appeared telling me that a ' HP Scanjet 4p' was found. So far, so good.

But the scanner doesn't work. I've downloaded the v2.8 Software for Win98 (in german) from the HP Website and installed it. When I start the Scanner-Test, an error is displayed (after approx. 2 minutes): 'TEST FAILED: Scanner internal self-test failure.'
When I click on the 'Info'-button, another window appears: 'Scanner-Statuszeichen: 1111111111212345678901234567890PPPPPPPPPPPPPPPPPPPP'

Is the Scanner broken and has to be repaired ?

Check in Device Manager to see if there are any conflict (Exclamation marks will indicate if there is a problem). Also If scanner is coming up under "Other Devices" remove all of these and re Plug'n'Play the scanner. Let me know how you go.     ;-)

is the scsi card you are using a standard scsi2 card?
make sure the card is not ultrawide and non ultrafast as the scanner may lose communication.
check to make sure the scsi card has no conflicts and f it does remove and reinstall the driver for the card
you could also try the hware test by turning the scanner on and off and observing what happens - if nothing happens you will know you have a hardware failure

Hello Andre,

When you first plug the scanner in and turn it on the scanner should turn its light on for about 30 sec to 1 min, the carriage should move a little and then the lamp should turn off. If this does not happen or the light stays on you have a hardware problem. You can contact customer support for repair options but it will probably cost more to fix than it is worth.

Connect further...control easier

Thank you for your answer, but my scanner behaves exactly like you described it. When I turn it on, the lamp goes on and the carriage moves a bit. After approx. 2 mins, the scanner turns off the lamp and the carriage moves forward and then again backward. For this test, it makes no difference if the scanner is connected to the Computer or not.

The Windows device manager tells me that the scanner is working correct (no exclamation mark).

If it takes 2 miniutes for the scanner lamp to turn off then there is a problem with the scanner.

When the scanner is first pluged in it does a self test and initialization / calibration of its ccd and optics. If the scanner cannot do this for some reason in two minutes then the code in the firmware tells the scanner to turn off the lamp and basically shut down.

Does it take exactly 2 min for the lamp to shut down?

I've taken the time until the scanner turns off the lamp a few times with a stop-watch. The scanner turns the lamp off after about 3 Min., 30 sec.

In case this means that the scanner is broken, do I have to contact the HP repair service, or could I do some self-service before I ship it to HP ?

Hello Andre,

Unfortunatly the optics are out of alignment. The only thing that can be done is to send it in for repair.

I have to tell you though on this particular product the repair will cost upwards from $150 to $300 dollars.

The 4p is a 300 dpi product. For $300 dollars you can buy a pretty nice 600dpi or 1200dpi scanner.

One other option is to call HP service and see if they offer the "Trade In Trade UP" program. It might save you $50 to $100 dollars.

I hope this helps

I just read your original question?

Where did you buy it from and did they offer you a warrenty?

If they did is it manufacturer or seller warrenty?
