Check your printer setup/default settings on the printer. Make sure you are using the right paper in the trays and that they are set properly to the proper paper tray & size. You have to have it right in all locations for it to work right, or it will default to by-pass tray. 1st in the settings, 2nd in the trays, and 3rd in your printer software. Good Luck!!

Please the copiers models.The paper tray is selected in the computer.To the Ricoh copiers the by pass cassette selected mannually.

Do the calibration for the scanner.

1. Place letter- or A4-size paper in tray 1, and adjust the side guides.
2. On the control-panel Home screen, scroll to and touch Administration.
3. Touch Troubleshooting.
4. Touch Calibrate Scanner.
5. Touch Calibrate to print the first pass of the calibration target(Print out).
6. Place the first pass of the calibration target face-down in tray 1 so that the arrows are facing into the MFP.
7. Touch Start to print the second pass.
8. Place the calibration target face-up into the ADF, and adjust the side guides.
9. After the calibration target has passed through the ADF once, reposition it face down in the ADF and touch Start.
10. Place the calibration target face-down on the scanner glass, touch Start, and scan the page.
After this pass, the calibration is complete.
Calibration will fails if print quality is not good...ensure that print quality must be in order..
Once calibration successfully done, restart printer several times & verify start button light, if its green every time 'u' re success. if not cleaning required for CCD which is major work & not suggestable..

We have become aware of an incompatibility between the ZoomAlbum software and the Canon PIXMA printers listed below. This issue applies only when using the ZoomAlbum software to print Photo Album covers with Mac OS X.
Affected Models
PIXMA MP240, MP250, MP480, MP490, MP560, MP620, MP640, MP980, MP990, MX320, MX330, MX860, iP3600, iP4600, iP4700 Printers
Phenomenon
The affected PIXMA printers are designed to feed paper via the rear tray with a center-feed mechanism and two paper guides. However, the ZoomAlbum software was intended to feed paper from the rear tray in printers with a right-feed mechanism and a single paper guide. As a result, when using the ZoomAlbum software with Mac OS X to print Photo Album covers with the affected Canon PIXMA printers, the printed image may shift.
Countermeasure
To remedy this problem, please use the following settings when printing Photo Album covers with Mac OS X:
1. Click System Preferences
2. Click Print & Fax
3. Select your Canon PIXMA printer as the default printer
4. Select DL Envelope for Default Paper Size in Page Setup
Note: Be sure to change the Default Paper Size back to Letter after printing the cover.

It sounds like the driver provided by the manufacturer may have a glitch in it. I would recommend sharing the printer to the MAC:

Add the Shared Printer to Your Mac Launch System Preferences by clicking its icon in the Dock.

Click the ‘Print & Fax’ icon in the System Preferences window.

The Print & Fax window will display a list of currently configured printers and faxes that your Mac can use.

Click the plus (+) sign, located just below the list of installed printers.

The printer browser window will appear.

Click the ‘Windows’ toolbar icon.

Click the workgroup name in the first column of the three-pane printer browser window.

Click the computer name of the Windows machine that has the shared printer connected to it.

You may be asked to enter a user name and password for the computer you selected in the step above.

Select the printer you configured for sharing from the list of printers in the third column of the three-pane window.

From the Print Using dropdown menu, select the driver that the printer needs. The Generic PostScript Printer driver will work for almost all PostScript printers, but if you have a specific driver for the printer, click ‘Select a driver to use’ in the dropdown menu, and select the driver.

Click the ‘Add’ button.

Use the Default Printer dropdown menu to set the printer you want to use most often. The Print & Fax preferences pane tends to set the most recently added printer as the default, but you can easily change that by selecting a different printer.

I connected my HP5MP to the DP-300U LPT1 port.
I configured my port on the DLink Configuration tab, giving it a name "hp5"
...The default login is at http://192.168.0.10/ user:admin pass:(there is no pass by default)

On my Mac, I go to System Preferences > Print & Fax
Click the + to add a new printer
Select the IP option
Choose the Protocol: Line Printer Daemon - LPD
Type in the Address: 192.168.0.10
Type in the Queue: hp5
Print Using: Generic PostScript Printer or better yet, 'Select a driver to use...'
and find the driver for your HP LaserJet 5MP.
Save it. Works like magic. ;-)

If you change the IP address or password on the DLink, just CYA and write it all down on a sticky note then tape the note under the DLink chassis. There's no reset button on the thing, and if you're o a Mac, you won't necessarily have access to the Windows utility to jack with the DP-300U. So, write it down, kidd-o!

check your mac connection settings, change if needed, try install new printer.
