Hi im looking for some help, my printer when switched on reports that tray B is OPEN,i have checked for jammed paper etc, nothing t5here at all.
do u think its a sensor thats blown, or dirty, the printer is only 1 year old and not had a lot of paper printed from it.
any ideas on how i can resolve this issue and get my printer working again would be helpful.

Got same problem. Idiot Epson service manual uses too many acronyms such as "MSI" - what the hell is MSI - We don't all speak Epsonese and even a search in the service manual does not give a description. Anyway, the manual gets you to check all the other cover sensors, even though they can be easily proved to be working because they show the status in the display (A, B, C, E, F OPEN) if all open. Close any one of them and the corresponding letter disappears so I know all switches working. Have manually checked to B switch, ,metered it ok, cable ok so I'm suspecting main board. Did you ever fix this one? - too many people post problems but never their own follow-up to save other people going through same thing.
By the way I love the wording of the next message if you press the "Go" button while "B open" is displayed... "Unable Clear Error" - they really need proof readers.Got same problem.

Interesting point of detail - may or may not be related. When the "B Open" error is displayed, if I open another cover (say A), the "B Open" is replaced with "A Open", but any further covers opened get added in the display so the maximum number I can have open displayed is "A C F E Open" - (there is no D on this model. But it never shows "B" except when all the others are closed. This I think is significant but until the fault is diagnosed I won't know why. I would need another working C1100 to compare these symptoms. I'm hoping the customer will write it off though - indications are PWBA MCU and/or LV/HVPS faulty. IMHO uneconomic to repair.

Re: epson aculaser c11oo
Best guess would be that the lever on the sensor for the cover that is reported as open has got bent.
Get yourself a service manual from
http://www.TheServiceManualShop.com
and find where the sensor is that is affected. Visually inspect it and ensure it works when the cover is opened/closed.

Pull Carefully If the sheet of paper is visible at the
output slot of the printer (in other word, it stopped on its way out of
the printer), try pulling carefully on it. If it pulls smoothly and
easily, then carefully pull it the rest of the way out. If there is
resistance, then stop and go on to the next step.
Open the Cover Open the printer cover and wait (in
the case of an inkjet printer) for the carriage to stop moving.
Carefully, slowly pull out any paper that is caught there.
Take Care Do NOT pull paper out from where it was
feeding into the printer (where the blank paper enters the device). The
rollers on your printer may only go in one direction, and if you force
them the wrong way, you could damage the machine.
Be careful of the following:
Laser Printers If you have a laser printer, be very careful when pulling out the paper -- laser printers can get hot.
Paper Shreds If any paper tore, either during the
jam or while you were removing them, remove any appliances that you can
(paper trays, etc.) and look for the shreds of paper. Try to make sure
nothing has been left behind.
If you have frequent paper jams:
Don't Overload Overloading your paper tray can cause
paper jams. Your manual may say that your input tray can hold 250
sheets -- but if you keep getting jams, try loading 225 sheets instead.
Check the Paper Check the minimum/maximum paper weights that your printer can handle. Paper that is too thick, or too thin, can cause jams.
The following is general advice that applies to removing paper jams in most printers, copiers, etc.
Switch off the printer at the wall and unplug it. Remove the paper tray from the printer. Check to see if the printer has an access door in the rear to allow you to see inside (open it). Open any other external flaps (eg. manual paper feed tray) that will allow you to see inside. Open any internal flaps or levers designed for user operation and usually indicated with a green or orange coloured tab.
Always remove jammed paper by pulling it in the direction of normal travel only. Don't try to pull it out against the direction that it entered the printer. Sometimes rollers inside the machine have a knob (usually coloured green or orange) that can be used to manually wind the page through the printer or fax. Always turn in direction of arrow indicated only.
After removing page, return all levers, flaps, doors, paper trays etc to original positions, reconnect power to the printer and test
Presumably this error follows an actual paper jam (whether the culprit has admitted it or not). The following is general advice that applies to paper jams in most printers, copiers, etc.
In my experience at least 98% of paper jam errors are because a piece of paper is still caught inside the printer. The remainder are generally due to a damaged paper jam detector (usually a small plastic arm which actuates a switch inside the printer) or less commonly a failure on the PC board which senses paper jams.
Please return to point 1 and look (again) for a piece of paper jammed in the printer. If the jammed paper was torn from the printer, only a small remnant has to remain inside the printer to generate an unclearable paper jam error.
Switch off the printer at the wall and unplug it. Remove the paper tray from the printer. Check to see if the printer has an access door in the rear to allow you to see inside (open it). Open any other external flaps (eg. manual paper feed tray) that will allow you to see inside. Open any internal flaps or levers designed for user operation and usually indicated with a green or orange coloured tab. Occasionally a page can wrap completely around a roller and be very hard to see. Be very suspicious of any 'white' roller' - check at the ends to note if the roller is actually a different colour with a complete page wrapped around it (generally then only removable by tearing other than complete disassembly by a professional). If paper was torn you may need a pair of tweezers and some determination to remove any small paper pieces wedged inside the printer. Ensure the printer is unplugged from the wall and avoid damaging any rollers or other parts inside the printer. Always remove jammed paper by pulling it in the direction of normal travel only. On rare occasions very serious paper jams may need expert service to dismantle and reassemble the printer.
After finding and removing all paper pieces, return all levers, flaps, doors, paper trays etc to original positions, reconnect power to the printer and test.

OK, if the printer says jam but no paper inside and prints after you open and close the cover the paper likely never made it out of the tray. Or the machine thinks the page never made it out of the machine.
As far as input check your rollers 1 in the tray and the pick up roller in the machine if you don't have alot of pages on the machine these likely OK.
Next (and this I have found often) check the paper back stop in the tray. This is the guide to set the length of paper. If it is set just a little long the roller cannot catch the edge of the paper. Sometimes the teeth the guide sets in are broken or worn.
The output would be the sensor in the fuser replace fuser.
Hope this helps
. Switch off the
printer and disconnect the power supply. Allow any residual charge
inside the all-in-one printer to dissipate before putting your hands or
any metal tools inside the chassis.
2. Pin down the exact
location of the jam. The 3 hot spots for a jam are before a sheet
completely leaves the paper tray, anywhere between the feed tray and
print carriage or between the print carriage and output tray.
3. Take off the front
paper tray if the sheet jammed while still in the front area of the
printer. If here, you should be able to see most of the paper.
4. Pull the sheet with
both hands and steady pressure. Do not tug as you might rip the paper,
leaving a piece deeper inside the machine.
5. Open the back panel to reach paper jammed between the feed-tray area and print carriage. Carefully remove the jammed paper.
6. Use the carriage
access door to get at a jam further inside the printer. You may need to
remove the print carriage to get to the jam.
7. Replace all parts and
return any access panels to their closed and locked positions. Plug
your printer back in and flip the power switch.
cheers m8 looking at ur suggestion at the weekend.
tnx for taking the trouble to assist me.
