Hp q2485a this printer has worked using both trays using windows vista....how can i have printer print both types of paper

SOURCE: Printing problem with HP Laserjet P2015 printer

This can be an issue with one of the faulty sensor across the printer.
Please check if you are able to print from tray 1, e.g. a configuration page.
A config page can be printed by holding the Green Button and releasing it as soon as the Triangle light comes on. This would take approx 5 secs.
If the printer is able to print from tray 1, then it could be an issue with the tray 2 pickup sensor.
Check if the tray 2 pickup sensor ( a black plastic piece to the right of the tray 2 pickup roller) is moving freely (front and back), also check if tray 2 pickup roller is not able to rotate completely.

If the tray 2 sensor is not moving freely and of the pickup roller is rotating completely, then reseat the pickup roller.

Normal use with good media causes wear resulting in the need to periodically clean or replace the pickup roller. Additionally, the use of poor media might require more frequent replacement of the pickup roller. Replacing the pickup roller Complete the following to replace the pickup roller:

CAUTION: Failure to complete this procedure might damage the printer. Unplug the power cord from the printer, and allow the printer to cool.

Are you getting the paper mismatch error message?
If yes, see below...
I will ignore the normal solutions to a "paper mismatch" error such as your settings not matching your printing media. Obviously, check these first:

If your problem is not solved with the above steps, you have an issue with your "spot sensor" and it needs to be calibrated. Instructions:

1. Press * and # at the same time, and then release both keys.
The display reads "Enter Special Key Combo".
2. Press 3, 2, and then 9, releasing each key before pressing the next. 
The display window should read "Service: R0622M" with a revision number. 
3. Press the right arrow button once.
The display should read "System Configuration".
4. Press Enter or OK.
5. You will be prompted to enter serial number. Do not enter any information
on the unit.
Press the right arrow button until "media sense calibration" appears in the
display.
6. Load Paper into the unit and then press Enter or OK.
7. Media Sense Calibration process will take place.

3. If the product is not already on, use the On button to turn it on.

1. Replace any paper that is ripped, dusty, curled, wrinkled, or bent.
2. Make sure that all the paper is the same size and type. Because only one type of paper can be used in the product at a time, paper types should never be mixed.
3. Tap the stack of paper on a flat surface to align the edges.
4. Make sure that the stack of paper to be loaded in the product contains no fewer than 10 and no more than 25 sheets of paper.
   NOTE: Do not load too much paper in the product.
5. Insert the stack of paper into the product and gently push the paper guides snugly against the paper. Make sure that the paper is completely inserted into the product and can be picked up by the paper rollers.
6. Try printing again. If the issue is not resolved, try loading different brands of paper and different types of paper, one type at a time, into the product and then try printing again.If the issue persists, continue with the next step.

3. Clean the rubber rollers with a lint-free cloth, lightly moistened with water.
