Hi we don't use our printer all that much and now we have a problem with the black print head.

We always let it do the 12hr print schedule and used the printer to print 50 % coverage 4 meter job yesterday.

Here are 2 pictures for before a few cleans and now.

I'm a little confused here...the second pic you uploaded looks like it's fine..so is your problem resolved? Or were they uploaded in reverse order?

Could be a cap top, but would need a little more information here

Watch for dried ink in the captops around the rubber seal. If drain lines sit for a couple days you can have ink dry up in them and cause a blockage. If during cleanings you see ink run out of both drain lines then you should be good there. If cap tops (filters) swell they can touch the underside of the heads and cause issues. The heads themselves can get a bit of blockage so that the lines miss fire and cause a test print to look wavey. Also if the wiper blade is dirty it can cause the same look caused by the head not getting wiped off propper and leaving globs of ink over the head.

Most of these are fixed by using a swab and cleaning fluid and cleaning around the heads and captops as well as wiper blade.

Take care not to rub the heads where the print jets or nosles are. Go around the outside of the head area as shown in the manuals for manual cleaning.
