Hello themamadonna,
Welcome to the HP Forums! I understand your concerns with your Photosmart A636 Photo Printer. Please print a "Self Test Page" to verify if you are receiving a blank page:
1. On your printer: touch the Setup icon to display the Setup menu.
2. Touch Tools, then touch Print Test Page.
If you are receiving a blank page, then please follow this HP document on Print Quality issues.
Looking forward to hearing from you.
