T1300 Postscript cutter causes error 86:01

[remstaler]

Hi ,

i having here a T 1300 Postscript plotter who gives me some headache . During initialization the carriage drives all th eway to the left engaging the cutter to the down position , then it moves over the rail a bit until it gets resitent , so far all is normal , now the carriage move back to the left to release the cutter from the down position , here comes the issue . It is not moving far enough to the left so that the cutter is released and its trying to move with the cutter in down position to the right , direction park position. then it troughs out an error 86:01.

When i remove the cutter from the carriage , it does the initialization normally without error , and i can print without issues and the cutter cuts the paper after installing it again. if i then reboot the plotter , the very same error comes again up.

Is there any way to reprogramm the cutter release position for some more cm to the left ?

Sounds you should just replace the cutter.

On startup, the carriage should bump the cutter on the left but not pull it back to the right. If it is, then something is wrong with the mechanism on the cutter that catches/releases the carriage.

i have tested with a cutter from a machine who is working . it does the same . On startup it bumb the cutter to the left , goes slowly to the right stops the direction and goes to the left again to release the cutter,,, as far i can see it not goes far enough to the left to the release position and tries then to go to the park position, thats when it jamms and troughs the error out .

i tried today the axis analysis,,, it starts , moves all the way to left and right and then says the axis need lubrication,,,, if i move it by hand it moves smooth,, i add oil on the axis all the way ( fine light oil ) and repeated the process 3 times ,,, same error ,,, axis need lubrication .


But on the standard initialisation all works well without error . Only if i mount the cutter it get stocked. If i let the initialisation finish and mount the cutter afterwards, everything is working fine , it plotts , it cuts , without error.

this sis a weird issue.

Re: T1300 Postscript cutter causes error 86:01

Forgive me if my memory isn't correct here....

On startup, the carriage should move all the way to the left, bump the cutter, and then move to the right without pulling the cutter with it. Is this what you're witnessing?

If it IS pulling the cutter.. then that's wrong. (Again, I'm going on memory.)

Make sure the encoder strip is clean and installed correctly. You might want to remove the encoder strip and hold it up to the light and make sure there's no clear/worn spots along it. If any of those tiny lines are missing it will throw off the carriage's movement.

Make sure the cutter wheels are on the little bump on the cutter rail.

I suppose it's possible the 'hook' on the carriage is broken somehow and it's able to pick the cutter up but not release it. Unfortunately I don't have one to look at.

On this t 1300 model the cutter is Fixed assembled with the carrier . it is moving all the time with it . I will try to swap the encoder strip with another machine that i have here and see whats happend .

Re: T1300 Postscript cutter causes error 86:01

I apologize; I should have looked at the service manual first! You're right about the cutter being attached to the carriage.

There is a blue plastic piece screwed into the rail the carriage rides along, on the left side of the printer. (It's what you have to remove to replace the cutter on other models.) I believe that's what flips the cutter up and down.. I'd inspect that. Make sure it's in the correct position.

With the carriage unparked and the power off, you should be able to slide the carriage into the left side and manually engage and disengage the cutter, to see if that's working correctly.

i didn't recognised a blue plastic piece on both of the T1300 models i have here . i moved the carriage with power off and i can engage and disengage the cutter without issues . What i saw is that on the machine where i have issues the carriage don't move far enough back to disengage . It is missing about 5 cm . could it be a encoder strip issue ? i saw some ink on the very right site on the encoder , close to the parking position. i have tried to remove it with alcohol, but it looks like the ink is somewhere between the plastic sealing of the encoder and the metal itself. I will try tomorrow to replace the encoder strip with one from a broken machine.

You should never use alcohol to clean the encoder strip. It will melt/cloud the plastic. Just use water or Simple Green.

It does sound like an encoder strip (or encoder sensor) problem.

Is the belt OK? Is it a genuine HP belt? I had a customer use one they got from China and it caused all sorts of weird problems.

The blue piece is the one in the picture attached. I realize this isn't the same model printer (with the other style cutter) but I beleive this piece is still installed on the T1300. I saw it in the service manual images, anyway. Again, I'm going by apparently very foggy memory here.

thx for the tipp for not using alcohol. The belt is ok, the plotter dont have a lot of working hours , still all original parts in . The blue piece is definitely not in the T1300 . Will try to swap encoder strip and revert back .

Thx

Re: T1300 Postscript cutter causes error 86:01

Well. Now that I've looked at the manual more carefully, I've noticed that they used images from a different model printer in places, which shows the other style cutter and that blue piece I mentioned.

So I'm just going to sit over here and be quiet. I'm sorry for all the confusion.

Re: T1300 Postscript cutter causes error 86:01

I would probably start with the encoder strip.

i have cleaned and checked the encoder strip. The strip is in very good conditions , no scratches and all tiny lines and marks are still there .

The cutter issue during the initialisation is still there .

any other tips ?

Have you tried the carriage calibration in the diagnostics menu?

Re: T1300 Postscript cutter causes error 86:01

yes i have tried this several times, it always stops with the message that the carriage needs lubrication. i have lubricated the carriage already a couple of times , with very thin oil ( WD 40 ) and when i move it from hand it moves smooth , but during calibration it trows out all the time the same message and didn't finish calibration.

During regular printing , all runs fine without error.

Re: T1300 Postscript cutter causes error 86:01

At the risk of sounding like an ass, I just want to note; WD40 will melt plastic. Petroleum products dissolve other petroleum products.

The bushings in the carriage are plastic.. that's why HP supplies synthetic oil with the printers.

You can use paper shredder oil too in a pinch.

A 3.5oz bottle (which has lasted me about 10 years) is $32 from HP. P/N 6040-0855

Under the Scan Axis test menu, there should be a choice to test the cutter. What happens when you do that?
