HP office jet 7510 Printer (repairs (Hillsborough, Sheffield S6)

(Spares/repair) Good solid HP printer/scanner, but has recently stopped working, not sure if its simply because it needs yellow ink or if its actually got an issue with it. Someone with the time/knowhow will probably be able to get it running or use it for parts.
Please note Its quite big/heavy.
Size is approximately: 60cm wide x 30cm height x 30cm depth
Collection from S6 Sheffield.
Just had 2 new inks, so 3 out of 4 are near enough full, but the yellow ink has completely out. See error message on pics, could be a simple fix.
 I will leave it wrapped up outside my door for you to collect this weekend.
Message for full address, im very busy so just take it, Its First come first served.
