Epson 7900 - Moving It Upstairs- Avoiding Clogs
Pros: The exterior end caps are strong enough to stand on-end.
Cons: Manual diagram is misleading. It does not take four people to lift the 7900. Yes it is heavy but two men can do it.
I am a photographer by hobby. It had been frustrating to deal with so-called print labs that refused to take TIFFs, or only offered photocopy output, or only offered 150dpi. So I said, "To hell with that." I saved up the money then purchased a 7900 HDR. I knew this thing was going to be big, but never expected a delivery via 18 wheeler. It arrives on a pallet with a shipping weight of 320#. Do not expect the driver to haul this into your home. The dealer's obligation ends once it is at your address. I got mine from Adorama. They used Oak Harbor Freight to ship it. The huge box arrived in excellent condition considering it travel cross-country. The driver used a hydraulic forklift to roll it into my garage.
Peel off all of the labeling in case you need it later.
After cutting the shipping straps, one person can lift off the box. It ships without a bottom.
Remove the stand box which is on top. Haul it upstairs and assemble it.
Now, take a very long look at the shape and size of this head unit. Find the grip points. Think long on how you will need to turn this around and maneuver it through the door and up the stairs. If you don't have arms like Sasquatch and cannot lift 200# above your head, don't even think about moving this on your own. This is a two man job.
I have read online that these units can be turned on-end without damaging the printer. I did that and it was fine. You should place large panels of cardboard on the floor where you will need to pivot the printer at the base of the stairs and at each landing on the way up. One side of the unit is heavier. Position that on the bottom. Two men can lift this thing as long as you don't get cocky. Travel one step at a time. Place the unit on-end at the top of the stairs and pivot it where you need it, then lower it to the floor. Here is where you rest, high-five each other, and shout "You da man!"
The stand should be assembled and the wheels locked. Lift the unit and carefully rest it onto the stand. Make sure it is stable before taking your hands off of it. It makes no sense to end up weeping after all of your hard work, not to mention money. Check under the head unit to confirm that the two pegs are inserted into the bottom of the unit. The wing-nut brackets should be aligned with the threaded holes (2). If so, you are done. Tighten the wing-nuts.
Now read the @$#@$ manual!
After reading online about print head clogs on the 7900 I found additional anecdotes on how to avoid most of them. It's pretty simple. Use the printer often, and keep the wiper blade clean. The print head cleaning via the control pad on the machine can make the clog worse, especially if the problem is on the wiper blade.
The blade can be changed for less than $20 (if you don't call Epson to do it for you). If you are careful with it, try cleaning it yourself. This should be simple as long as you clean it often (after a day of printing). It might also be prudent to re-agitate each ink cartridge before a printing session. Just be very careful not to traumatize the little IC sensor on the side of the cartridge.
After all you did not spend this amount of money to expect the 7900 to just be another desk-side printer. You would not have purchased a Ferrari to occasionally drive to the cleaners. So, to avoid being taken to the cleaners, use the damn printer often. I am waiting on a second ink-set to avoid having my new 7900 sit idle after depleting the startup set post initial charging and diagnostics. I will be monitoring my ink levels and ordering more stock at 50% depletion on any cartridge. Time will tell if my approach is the right one or if I am just blowing smoke.
Well, after entering maintenance man mode I found the menu sequence to expose the wiper blade. Note to self: Don't expect the machine to tell you if you were successful getting into maintenance man mode. You just have to go into the menus to see if the options have changed. Release the three buttons as soon as the inkwell display appears and you are in.
Removing the wiper blade assembly is too easy. ($300 for Epson to do it.) You need to be careful removing it and reinserting it. Do not touch the rubber blade with your bare hand. After printing 4 large images, my blade had noticeable ink on one side. It was still wet after sitting overnight. The ink deposit can be cleaned with water via a soaked lint-free paper towel. I cut the paper towel into quarters, folded one piece and then soaked it with water. Gently wipe the ink from the blade with the end of the paper. No pressure is required. Be gentle at all times. If the ink was wet when you started then all of it will wipe off. Afterwards, use a dry quarter paper towel to pat off any water droplet. Take a long look at the blade to assure there is no lint left behind. Check the assembly for dust. Remove it if you find any. Reinsert the assembly the same way you took it out. Close the cover, wait for the machine to acknowledge your fine work. This may take a few minutes. Eventually the please wait message disappears.
This is a simple P.M. routine, once you break the secret Jedi Code of Epson. I am not a professional printer, but it seems logical that if you keep the cleaning mechanism CLEAN, then the print head should remain clean without having to flush significant ink into your maintenance tank. Just charging the ink lines on initial power-up used 38% of the maintenance tank. I have turned off automatic cleaning. I know Epson expects to make a good profit on ink sales, but dumping more ink to free a non-clog seems silly to me.
