The plotter ran out of paper and all the amber lights where on. I loaded a new roll and went to feed it as usual and saw that the lights where still lit and the paper would not feed. There is a cancel button above and all lights went out except media. I went to feed the paper again and it would not go.I tried turning the unite on and off but that did not work. It did you out of paper during a print and I pushed the cartridge carrier back.
I agree with Green Saints, if its only media light it is your top cover open. However this sounds like your carrage is not running. You firstly need to check the belt. Look at the belt, is it not shredded or visually perished and letting off a lot of pinkish pieces and dust. If the belt is ok then with machine off, move the head to the center and (if you presumably dont have the correct oil) use a drop of sewing machine oil on either side of the head, move the head left and right slowly to smear the oil the entire length of the rod.It should then be ok

I would check the sensor on the carriage that detects paper. It might be dirty enough that printer cannot detect the subtle edge of the clear film. It is the blue light that turns on on the bottom of the carriage when you load paper.
I could't understand the question exactly..I will try my level best, it may helps you..
T770 plotter having three media paths..
1. Sheet path
2. Roll 1
3. Roll 2..
After initializing, printer will ask to load the media, you have to specify the desired media selection ie sheet, Roll1, Roll2..
If U R selected roll one, message appears on screen "Open Roll 1 cover", you have to follow the message, once the paper is loaded in the path, printer has to detect the paper,it has to pull inside with the help of the roll feed motor.. In this case If UR selected Roll 1 on printer screen & inserted Roll 2 media, printer will runs Roll 1 motor, not roll 2 motor.. This problem U might be facing..
If my suggestion is not helping U, pl let me know exact problem what UR facing...
Its common problem in T Series Plotters:
Cause of malfunction: These plotters having separate sheet path as well as roll path for print media. After initializing plotter its verify the available media(sheet or roll). If sheet path is occupied by the media it wont allow the roll media, means first priority is for sheet.If sheet path paper sensor dusty or malfunction, printer will say "remove paper from sheet path" even no paper in sheet path..
How to shoot this problem:
You need to clean sheet path sensor located at sheet loading area.(black 'U' shaped part) Applying the pressured air at sensor is the best method to clean.. If problem remain you need to remove the sensor & clean or replace it.
Follow the snaps:
Need to open roll feed right side portion
Clean the IR sensor...
Fix it back..
Note: Technical knowledge required to understand the remedy..
there is a common fault on this particular printer which also affects the t770/t1200
when trying to feed a new roll of paper the plotter is asking to remove the paper from manual feed even though there is none.
the fault lies with the way the plotter is using the manual feed sensor,
there has been a technical release from HP regarding this same issue.
what to do -
1) firstly you need to find out whether the sensor really is at fault or if there is another fault which is confusing the manual sensor output.
a:- upgrade the firmware on the plotter ( always make sure your plotters firmware is upto date), cycle the power of the plotter and retry.
b:-use your user operating guide to take you through 'calibrating manual feed sensor' and retry.this is a quick process which sets the values for paper present/not present on the formatter.
c:- if the above two have failed then order a new PCA and calibrate the sensor immediately after first initialize of new Main PCA.
if the sensor fails to calibrate then I would first order a new sensor ( cheapest option first) if that fails then replace the main PCA. but always first check for any new firmwares.
Here is what I've found out by trial and error.
Paper Roll Won't Load:
-Usually occurs when the roll is less than 50% full
-Printer will give the error "paper loaded askew"
To Correct This:
- Press and hold Stop until Job Cancel comes up on the
- Press Menu
o Scroll Down until Adjust Printer menu comes up
o Press right side arrow next to OK button
o Scroll down to Manual Band Adjust and press right side
arrow again (or select one of the other adjustments)
- Select Yes and press OK
- Load paper roll - make sure paper is straight
- When asked (printer will beep) select Plain Paper and
- Let paper load
- When printer starts to print press and hold Stop to cancel
- Paper should now be loaded
When all else fails load a new roll.
This would be a temporary solution until the sensor is fixed.
When you load the paper, the carriage edge detector measures exactly where the right edge of the paper is located. Then the paper is rolled forward and the edge is measured again. If there is a difference in the measurements, the printer assumes the paper is not loaded squarely and rejects the paper. After you load the paper and the printer asks you to align the paper, take your time, release the paper with the release lever, and line up the right edge of the paper with the right edge of the paper roll. You might have to do it more than once to get it to load. Some plotters are very sensitive and others are more forgiving.
Take out your paper (check if you are loading the roll from "underneath" and not from the front) . Switch off and on. If the machine gives you the same fault again, press cancel for about 2 seconds, it should then go to ready mode. If it does not then you have a carrage sensor failure. In any case the sensor is failing and its finding it difficult to find the paper. Its a bit technical but if the sensor fails you will need to replace your carrage (head) unit
The reason it could be the main board is that it tells the front panel lights what to do. This seems like a logical problem the printer is having, usually things freeze when internal memory is bad. Surely have the main board replaced. There is a part of the internal programming that it cant get past. Compare it with trying to read a sector of a cd-rom that is scratched.
I don't know if you are running in sheet or roll media, but we have this problem with roll media if it is not aligned properly. Usually if I release the media lever and pull 10-12" of paper through and align it with itself and with the dotted line to the right of the plotter, then it will accept it. Sometimes takes several tries. Sheet problems may be caused by dirty sensors. Good luck.
