Out of media

The 750C starts to print and after a few passes it stops and says "out of media"

Then prompts me to insert a sheet or roll.

I always use roll media and there is plenty of media

    I blew off the sensor but the problem still happened. I carefully removed the sensor and cleaned with a Q-tip and alcohol. It is currently working fine - Thank You

Look under the plotter on the control panel side. You will see a sensor with two wires comming out. This sensor is dirty. You can try and blow it clean (often works) or remove it and clean with a small brush. It clips in and out but be careful and take note of the clips etc remove it without breaking any.

Stop Ejection of printing paper roll after printing in dot matrix printer


I assume you are printing on roll paper, but printer acts like it is printing on cut sheet paper. When finish the page, it ejects it, but it is not a page, it is a roll and the paper keeps unrolling, right? There have to be a lever that swithes between cut sheet paper and roll paper. Turn it to the oposite direction and the problem should be fixed.

A1 rotation from A0 roll


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...

Remove roll from sheet path how


This is one of frequent error in this series.




as you know two types of media paths 1. roll media 2. Sheet media. In sheeteet media loading area, you can observe 'u' shaped(extremly right side where sheet media sits) plastic mould which paper passes through in it. This palstic mould contains paper sensor to sence the sheetmedia. If this sensor is dusty, printer will treats that sheet path accupied by media. The best method to clean this sensor is to blow pressure air in this sheet path area.bicycle pump is best for this process.. try it...

Red and green light turn after first run


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:

Hi i have just inherited a designjet 430,it is not connect to a computer as yet. i have loaded a roll of paper and ran some tests which seem to work ok except when i press the set up button the media light...


Either: the sheet you loaded is

misaligned.

Realign it again. See the Users Guide

for a short tutorial on loading media.

Or: it is an invalid size.

For supported media sizes, refer to the

Users Guide.

Or: the media lever is lowered.

Raise the lever.

Or: the cover is open when the printer is

initializing.
Lower the cover

These are the trouble shooting suggestions from the HP service manual

Printer header path type 1, 2, and 4 prolem request for feeding back


If the media does not feed into the in-feed slot in the media cabinet, try the following:
  • Make sure both roller levers are lowered to open the in-feed slot.
  • Trim the leading edge of the paper so it does not get caught in the slot.
  • Insert the media evenly to avoid angles. Do not insert one corner and then the other.
    NOTE: A beep means that the printer has detected the media in the in-feed slot. The printer will only beep once in a load cycle, if media is removed and reloaded the printer may not beep again if the load process is not re-started through the front panel.
Media does not advance If the media does not advance far enough into the in-feed channel in the media cabinet, the paper is slipping and the rollers do not grip the media. Try the following:
  • The pre-tension might be applied incorrectly. Always apply pre-tension by turning the star screw on the left side of the spindle. Never apply tension by turning the media roll or the spindle disks.
  • Clean the rollers using the cleaning procedure.
  • If the media being used is heavy coated, try changing the media.
Media jam in the in-feed channel If there is a media jam in the in-feed channel, try the following:
  • Turn the multi-roll feeder off using the power isolator switch on the connector panel at the back.
  • Open the media cabinet doors and lower the roller lever on both sides.
  • Turn the spindle to pull the media out of the in-feed channel and to collect it back on to the roll.
  • If the media is blocked, place the spindle in the park position for better access to the in-feed channel, and then pull the media edges in a downwards direction on both sides.
  • If the media cannot be reached because the roll has finished and it has not been ejected from the front of the printer, open the rear cover and try to remove the media from the motion control assembly.
    NOTE: Do not insert media with crumpled or damaged edges, trim the media first.
  • Make sure the leading edge is trimmed straight.
  • Make sure there is even tension across the width of the media.
  • Make sure media is aligned (the same amount of media is fed across the width).
  • Apply pre-tension the media.
When the printer is going to be unattended for a long period of time, it is a good idea to load and unload each roll using the LOAD/UNLOAD commands from the front panel (if the media loading procedure was not completed when prompted by the printer). This will ensure that each roll of media loaded is correctly aligned and that the printer is capable of loading/unloading each roll when requested by the print jobs in the queue.
Media misaligned When a "Misaligned?? message is displayed, the printer unloads the media. Press ENTER to continue and the printer will display the "Ready for paper?? status message. Do the following:
  • Check for even tension across the width of the media. If there is less tension on one side than the other, then the media is not straight in the in-feed slot.
  • There is a hole on the right side of the in-feed slot. Make sure the edge of the media is aligned with the left side of this hole.
  • Lower the roller levers on both sides and adjust the media so that tension is even across the whole width. Turn the spindle disk quickly two or three times away from you and then two or three times in the opposite direction. This will help to create an even tension.
  • Lift the roller levers on both sides and try to load the media again.
If this does not solve the problem, remove the media from the in-feed slot and repeat the loading procedure. Make sure the roll is against the right hand spindle disk (fully inside the roll core), and do the same for the left hand spindle disk. The printer verifies correct alignment using the blue line on the right hand side of the printing area as a reference. Media does not unload correctly If the media does not fully unload from the in-feed channel in the media cabinet, check the following:
  • Maybe there is not enough pre-tension. Always apply pre-tension by turning the star screw on the left side of the spindle three or four times (or more if the spindle is on a low retainer bracket). Never apply tension by turning the media roll or the spindle disks.
  • The spring applying pressure on the retainer bracket is loose and the spindle is slipping in the retainer bracket. Turn the multi-roll feeder off and turn the retainer bracket screw one turn in a clockwise direction.
Partial or blank prints If the print is partial or blank, check the following:
  • Check the multi-roll configuration in the printer driver: Check that the Has Multi-Roll Feeder check box is selected.
  • Check default roll configuration: Check if a roll is installed for the roll configured as default. If a roll is not selected from the printer driver, the printer will try to print to the default roll, and if no identical roll is available, it will not print the job.
  • Check Productivity mode settings: If the mode is set to normal and the roll has finished, the job cannot be printed.
  • Check cable connection: Check that the printer and any network cables are securely connected to the printer. Make sure the parallel cable is connected between the multi-roll feeder and the printer and ensure that it is also firmly connected between the computer and the multi-roll feeder.
  • Check media configuration: Make sure the media rolls are configured correctly.
  • Check document file: When printing files that are generated with versions of printer drivers for printers without multi-roll feeders, the header section of some file formats already contains information on the media. In these files, roll or sheet information corresponds to roll 1 in the multi-roll feeder. These files will print to the Default Roll. HP advises that the top roll (roll 1) is used as the default.

Can't select Velvet Fine Art media type when using sheet feeder as source.


I had the same problem, same printer. So with a little checking I found a solution. The paper has to be fed through the single page paper feeder. (See manual to setup. Can be downloaded from Epson.) Select manual/roll in the page setup section when you're ready to print. For instance, I was using 8.5 X 11 velvet, so select letter > then subset of roll/manual. After doing this velvet and other specialty paper profiles were selectable.

Designjet 1050C


the plotter measures the media automatically. There is no size setting,only type of media.If you want to print on 8.5x 11 only a few times,load a sheet to print on by simply lifting the cover an aligning the sheet on the blue lines ,on the right side.If you plot a lot,I suggest get a 11" x 150' roll.
hope this helps
