FAQ and Troubleshooting

You will find common printing questions and troubleshooting tips below. For information about making photocopies, visit The HUB website.

Can I print from my phone/mobile device?
Print drivers are not available for mobile devices. Use a web station, Virtual Andrew, or computer lab to print.

Is printing available for campus guests?
Yes, see Plaid Cash printing.

Where should I print high-volume or special (glossy paper, color) print jobs?
High brightness coated paper is available for the color laser printer in CFA. If you are using a manual feed to print in CFA, ask the operator for help. The operator will make sure your document is printed on the correct paper. Large print jobs, should be printed at one of the multi-printer sites: Baker Hall 140 corridor, Hunt Reference area, E&S Library or Wean 5200.

How can I tell if a specific Andrew printer is busy?
Visit the Printer Status page for real-time printer status.

What is a Web Station?
Computers that offer on-the-go access to email, a printer or web browser. See the map for locations.

Can I cancel jobs that I no longer wish to print? 

Yes, you can cancel jobs that are waiting in your print queue. Swipe your ID card or Plaid Cash card on the card reader at any print station. Select the job you would like to delete and choose the Delete button. Deleted jobs cannot be recovered. 

Note: Your print quota is not affected by any print jobs that you delete before pressing Print.  Jobs not printed before the expiration time are deleted from the print queue.

What is the cost per sheet?
Refer to the Quota page for price details.

Can I get a refund for a jammed or cancelled job?
Refunds are NOT issued for jammed, defective or cancelled print jobs. However, you may be eligible for a free one-time print job release. Contact Computing Services for more information.

How can I avoid printing blank pages?
When printing web pages, use "Page preview" to ensure that your browser doesn't add a blank page.

I sent a job to the printer, but it doesn't appear in the print queue.
It can take up to two minutes for your job to appear. Check your computer to be sure that the print job was sent to one of the print stations.

Is there a printer location with a manual feed option?
See the steps for using Manual Feed in CFA

I released my job from the print station, but the document didn't print.

  1. Check the printer screen to be sure that it is not jammed.
  2. If the printer screen indicates a paper-size error, follow the prompts to scale the job to an available paper size.
  3. If you are printing a PDF document from Adobe Acrobat or Adobe Reader, follow the Tips for Printing a PDF Document.
  4. Verify the printer is connected. See the Printer Status page. 
  5. It may be a problem with the print job. Try again to print again. If the job fails to print, email contact Computing Services.

Will my document print single-sided or double-sided?
Select the two-sided option in the print dialog box to change this. Older print clients will print single-sided by default. Download and install the current print client to print double-sided by default.

The popup client does not appear on my Mac.
Check to make sure you have the latest software/drivers. If you do and are still having problems, reboot your computer and try again. 

Still having problems? Make sure your computer is configured correctly:

  1. Select Apple System Preferences > Users & Groups > Login Options.
  2. Enter the admin username and password for your computer, if prompted.
  3. Click Login Options (bottom left side).
  4. Uncheck Show Fast User Switching (right side).
  5. Select Apple System Preferences > Security & Privacy > Firewall > Firewall Options > Enable Pharos Popup.
Try printing again. If the popup client still does not appear, remove and reinstall the software:
  1. Select Go > Computer > Hard Drive > Library > Application Support > Pharos > Utilities
  2. Select the Uninstaller and follow the wizard.
  3. Re-install the software again.

I am getting errors installing the software, or Windows Defender detected a Virus when installing. 
Please run Windows Update to ensure that your computer is up to date and re-run the installer.
