The pizza wheels on the ESP 1160 are a combination of single and double wheels that are spring mounted in three plastic holders that are held on to the mounting plate by tiny hooked pins at the back of each holder and plastic clips at the front. ( I recommend removing the pizza wheels before installing a CIS system. I had already installed the CIS, and it made removing the pizza wheels much more difficult since removing the top cover on the printer was impossible without removing the CIS cartridges, and I was afraid that to do so might cause ink spillage.) Without the CIS system installed, it may be possible to remove the wheel mounting plate entirely, which would make the following procedure much easier. There are, I believe, three screws that attach the mounting plate to the printer. The following procedure is what I had to use, since I could not entirely remove the printer cover and mounting plate. 1) Remove the screw on the left side of the pizza wheel mounting plate and the screw that is located beneath the print head when it is in parked position. To remove the screw under the parked printer head, follow the procedure for replacing cartridges. After the print head has moved to the far left, unplug the printer. Remove the right screw. You may then slide the head back to the parked position by hand. 2) Lift the mounting plate slightly, release the clips at the front of the plastic assemblies with a little sideways and downwards pressure, and each assembly should drop out. The clip and wheel configurations are different for each assembly, so it should be nearly impossible to replace them incorrectly. However, just in case, the left assembly has 7 wheel groups and 4 clips. The center assembly has 7 wheel groups and 3 clips, and the right assembly has 6 wheel groups and 3 clips. 3) The pizza wheels are held in place by springs that go through the center of the wheels and are held into the assembly by the design of the assembly and the tension on the springs. Each spring has an enlarged section on one side. Lift the enlarged end of the spring that goes through the wheels that you wish to remove with a penknife, needle, toothpick, whatever, grab it with a pair of tweezers (or your fingers if you are more dextrous than I am), and slide it out. The wheels will then fall out. All wheels are the same size, so you don't need to keep track of which ones go where. Remove all of the sets of wheels except those that line up with the edges of the paper that you are going to use. I believe that it is necessary to leave the wheels that grip the edges in order to insure proper tracking and to prevent the image portion of the paper from contacting any part of the printer while the ink is wet. I have not yet tried printing with all the wheels removed. I did find that the wheel configuration had to be the same on each side (double, or single), or the paper would turn as it came out of the printer. Single wheels are easy to replace, since they just snap back in. The double wheels are trickier because you have to thread the spring back through both wheels while they are in place in the assembly. 4) Replace the plastic mounts. Make sure that the tiny hooked pins at the back of the mounts are seated properly or you will not be able to reseat the clips at the front. Even when the assembly is properly aligned, it may still be difficult to reseat, but it can be done. If the assemblies are not reseated properly, they will press down on the paper and cause damage. 5) Replace the mounting plate screws. 6) Plug the printer back in. The print head should recycle back to the start position. 6) There are two additional pizza wheels mounted beyond the main banks of wheels which may also cause problems if the paper comes in contact with them. This should not be a problem unless there is excessive curvature in the paper ( I have run into this problem with Ilford Photo Gloss paper near the end of the roll). These wheels have two pins at the back which, when depressed, allow the assembly to be slid off towards the front. If these wheels are removed, care has to be taken to remove the paper as soon as the print is done, otherwise the wet ink may cause the print to stick to the printer assembly at any point of contact. I hope that I have covered everything. If not, feel free to contact me personally by email if you have any questions, or I can give you a phone number to contact me to walk you through the process.
