Printer will not print from tray 1 only MP tray, data light keeps blinking

not sure if your on copy mode or print mode ..close the MP tray door....turn off then on go to general setup select tray 1. not sure if your on copu mode or print the machine wants you to add paper to the tray that needs it. if you add paper dowes it still say"add paper" .if this is the case then the tray sensor is 1)broke2) pushed out of the way folded3) tray feed roller are not installed correctly no allowing sensor ..make sure your printer settings(properties) are set the that tray.

Not necesarily so, it depends on how you have the printer configured. To test the MP tray, use the arrow keys to get to troubleshooting menu, press check, use arrow keys to get to paper path test, press check, set tray option to tray 1, then print test page. Printer should feed from MP tray. If it does, then the problem is that you do not have the printer set to print from MP tray first or you have the tray options set to exclusive which means that if your print job asks for tray 2 then printer will not print from MP tray unless you specify MP tray in the print options.

When you ready to print your computer.please go to print properties setting paper source default or tray 1 or MP.MP mean multi pass tray.I mean front paper loading tray.

HP Support says “If the Ready light is blinking, and the Go light is on, it indicates Data in the printer memory is waiting to be printed. Pressing the GO button prints from Tray 1 or from another tray if Tray 1 is empty and the paper size is supported in the other Tray. Pressing the JOB CANCEL button cancels the current job and the printer returns to ready.
Make sure the paper size is correctly defined.

Please follow my tips ,When you print your computer before you go to print properties.Setting paper layout choice paper source and enable MP tray then print ok.
keep your mind before print you must be insert paper in MP tray.

depends on the printer, normal home use printer have only 1 tray.
office printer usually have multiple trys. and usually the default for that is tray 2. tray 1 is manual feed.

is this still a current issue?

When you print labels or envelopes you need to select the correct tray from the print menu. (File print or ctrl P) or the printer will think the normal paper tray is being used.

You can force the printer to change the tray after the print has been sent by pressing the continue button on the printer, just make sure that the normal tray has no paper in it.

Hi,

Hope this helps. Please check the printer properties before clicking Ok at print menu command. Now check the available paper tray handler. Try bypass, tray1 or MP tray.

Check also the default paper on Printer Menu command by pressing appropriate setup button. You can try also placing the paper on bypass try if available. The load LTR message means the machine waits a short bond paper on MP tray or on bypass tray.

Best regards,
