designjet 500ps gives error for paper jam, but will not power off

[hepSignman]

old designjet 500ps wide-format printer

Windows 7 PC connected via USB

Changed carriage belt yesterday.

This morning cleaned carriage rail with alcohol, then printed recalibration sheet.

The paper ran out too soon (the trailing edge of the photopaper reached the rollers.

Printer threw a paper jam error 86:01.

The message tells me to power off, clear the jam, then power back on.

But, when I push the power button, it just blinks, it will not power off.

When I unplug the printer to "power off" it comes back to the same error message.

Is there an interrupt I can do to power off, or exit from the error message?

The suggestion in the error message is to realign the printheads, but I can't escape the error message to do this.

Any ideas or escapes?

 Unplug the power &  plug it again, when carriage box moves little to the center  & unplug it again.

check the belt first, then encorder strip :

You must be sure what belt you were replace ?

because the genuine HP belt has horizontal & vertical & pulley must match the direction from left to right.

bottom of the carriage box has a marking & make sure to match the direction.

Other belts were only verticals & must use their own pulley & no need to match direction.

So check the belt, also encorder strip  ( not very tight & carriage box hard to move )

No, the carriage does not move at all -- it is all the way to the left in the parked position.   I am stuck in the error message.

(I replaced the carriage belt and it did have the vertical and horizontal sections, and I matched them per instructions

The encoder strip is fine, too, )

[jasonmiamifl]

so, the trailing cable connection was bad   ( to the pca mainboard, also the carriage box )

The most troublesome areas...      edges to the mainboard & carriage box bad & not connected properly.

You should see   error   11:11 ?   not 100% sure, just off my mind.

Thank you for your suggestions, but the problem is I am stuck in an error message and need a way to power off the machine and/or escape the error message so I can try some of these suggestions.

Right now, when I unplug the printer, then plug it back in, it runs the initialization (the carriage DOES run across and back)  but it returns me to the error message.

Is there some escape code I can use to get out of the error message?

[jasonmiamifl]

check & FOLLOW my first reply

[hepSignman]

Sorry, am doing that now. 

The markings on the bottom of the carriage box I don't see (instructions did not mention those) but I am diassembling everything now to duplicate the belt replacement process.

Thanks, I'll get back.

>>check the belt first, then encorder strip :

>>You must be sure what belt you were replace ?

Replaced belt with belt from LPScompters, made to (or exceed) hp specs. The has half of the inside with vertical ridges and half with horizontal ridges. 

>>because the genuine HP belt has horizontal & vertical & pulley must match the direction from left to right.

>>bottom of the carriage box has a marking & make sure to match the direction.

Don't see any markings o on bottom of carriage box

The belt's horizontal ridges match the pulley on the right side

The belt's vertical ridges match the pulley on the left side. 

>>Other belts were only verticals & must use their own pulley & no need to match direction.

>>So check the belt, also encorder strip  ( not very tight & carriage box hard to move )

encoder strip is tight.

[hepSignman]

Took covers off machine, loosened belt, check that it was properly aligned, (vertical ribs on left, horizontal ribs on right)

Powered up machine and pinted out page.

It printed complete 24 x 36-inch image but stopped before the cutting.

Error 86:01

This time the printer would turn off from power button.

Checked the paper path but did not see anything to clear.

Cleaned the encoding strip with soft cloth and plain water.

Restarted printer and it intitializes, then returns to the error screen.

Is there something special I should be looking for that is affecting the cutter?

I cannot see anything obstructing the paper path (the roll of paper is still loaded and printed, just not cut)

Thanks in advance.

From you last message & you did fix the first problem. That is good.

I never seen 86:01 myself & have no clue. Let someone else to advice.

If you have canvas or other thick material & make sure chose media correctly. for example, canvas,

you must chose canvas & printer will not cut. 

try to disable    cutter from the print menu   & see what happen.
