Hi there and welcome
I want you please to clean the print head on the printer
To do this
Make sure that the power is turned on.Hold down the Stop button until the Alarm lamp flashes orange twice, then release it immediately.The machine starts cleaning the print head.The cleaning will be complete when the ON lamp lights green after flashing.Do not perform any other operations until the machine completes the cleaning of the print head. This takes about 1 to 2 minutes.
Once done, tell me how the printing now looks please.
Can you run it 3 times again and tell me if this improves this
ok, manually clean the print head as we discussed using Q-Tips and a cloth and let me know if this improves it please
ok, though it should have been left to dry for 20 minutes but if you make a copy on the printer instead of printing from the computer, same problem?
From which program are you printing?
Do you have office installed?
ok, so the issue then is only when printing from filemaker?
We are :)
Power off the mac
Then start the Mac and hold down the Command and R keys at startup.
Hold these keys until the Apple logo appears. After your computer finishes starting up, you should see a desktop with an OS X menu bar and an OS X Utilities window
choose Disk Utility from the Utilities window, or from the Installer menu if you're started from an installation disc.
Click the First Aid tab.
Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
Select your Startup Disk (usually named "Macintosh HD").
Click Repair. Disk Utility checks and repairs the disk.
Let this complete and when it has, tell me if you still have the problem please.
