What does the button mean :/\/ that is above the! mean?

If you have the HP LaserJet P2035 (or P2035N), then the LED next to the circle with a small opening at the top indicates the printer ready state. (This symbol/LED is below the triangle with the exclamation mark and above the Go button and light.) If the light is steady, then the printer is ready to use. If the light is blinking, then the printer is processing a job. These apply when no other lights are lit.

If other LEDs are lit, then there is a problem with the printer. See the user guide starting on page 76 for the entire list of LED status patterns. You can find the documentation on the product support page: https://support.hp.com/us-en/product/hp-laserjet-p2035-printer-series/3662025/manuals . The current link to the User Guide is http://h10032.www1.hp.com/ctg/Manual/c01460703 .

I hope this helps.

Service manual above, above that a repair site, above that is a forum for help, above that is your user manual

If the error light is flashing it means that Either there is a paper jam in the machine or the back or front cover is open.

If the error light is ON, it means that there is no paper in tray one or manual tray. Some times from certain programs it will ask the printer for the manual tray because it feels that the margins are too big.

Try putting a piece of paper in the manual feed slot above the paper tray.

FLASHING ORANGE LIGHT ERROR MESSAGES


Try counting the number of orange flashes.
* two flashes means you’re out of paper or the paper is not feeding correctly.
* three flashes means there is a paper Jam or the output tray is closed.
* four flashes means the ink tank is empty
* five flashes means the print head is not installed correctly or not installed or is defective (before buying a new print head always try the cleaning instructions at the end of this post first.)
* six flashes means the inner cover is open or not closed properly.
* seven flashes means you counted wrong.....
* eight flashes means the waste ink absorber is almost full or full.
* nine flashes mean that a digital camera or video that is connected is not compatible with the printer. If a specific amount of time lapses without getting a response from the digital camera or video camcorder this will happen.
* ten flashes means it can not print to both sides of the page
* eleven flashes means the automatic print head alignment failed. (this can be caused by low ink levels, ink tanks not being installed correctly, the print heads being clogged. It can also be caused by the paper output slot being exposed to a strong light source (Press the resume /cancel button and move the printer to a darker location and try to align the print head again.
* check to make sure the lock lever is correctly positioned (down)
If the above does not work, align the print head manually by opening the printer properties dialog box and clicking the maintenance tab and then select the print heal alignment button on the left side, second row down.

Go to this site ... http://www.samsung.com/us/support/main/supportMain.do

Using their search tool, search your printer to find the owner manual. You will find the answer to your question and the resolution in that manual's troubleshooting section.

If you are related to the other Samsung question, "i need permanent reset software of ..." relolading the drivers may overcome this issue. I am more inclined to think you need service on the corona wire or at least a cleaning of it. Instructions will be in the manual.

It is possibly a jam warning or "printer cleaner head full" warning. Check your manual for what the canon warning lights mean for your particular unit.

A quick fix you can try. Unplug your printer, press and hold the power button and plug it in while holding the power button, it should reset your printer...

If the blinking still persist, have a qualified technician take a look at it...

AP position error [6A00] - Sheet feed unit (QM2-1220) - Logic board ass'y (QM2-1548)*1 Don't know it means but the service manual says the above
