Please keep in mind the following points: All frosting and ink ingredients are FDA approved, all materials that come in contact with the edible portion of the product, backing paper, ink cartridges, cartridge filling and printer rollers, are FDA approved.

4. Are the Kolor Kartridges and Frosting Sheets FDA and EEC approved?

Yes.

5. Are the Kolor Kartridges and Frosting Sheets Kosher?

Kolors and Frosting Sheets are kosher approved. See our Kosher Certificate here.

6. Can a Macintosh system be used with the Kopyjet system?

Yes. If you use a USB Printer and scanner you can print edible images on the macintosh. However you must provide your own macintosh compatible photo editing software.

7. Why is my system running so slowly?

Regardless of a computer's processor speed, if the RAM on the computer is full, the processing time will slow down considerably. The saturation of the available RAM is normally caused by a very large image created when too high a resolution is used when scanning. The higher the resolution, the larger your image file will be. For instance, an 8.5" x 11" color photograph scanned at 75 dpi takes up about 1.6 megabytes (MB). Doubling resolution to 150 dpi will increase the file size four times - to approximately 6.3 MB. Going to 300 dpi will increase file size to 26.2 MB!

What you need to do then is to select the lowest possible resolution that still gives you good image quality in order to keep file size manageable. Our recommendation is not to go any higher than 200 dpi unless you specifically require the resolution and are knowledgeable in image processing.

The banding is a result of the edible ink drying in the print head and restricting the flow of ink to the image. To eliminate the banding, the print head should be cleaned.

2. How do I clean the Canon print head?

It is almost inevitable that at some point your print head will become blocked and you will experience printing difficulties.

Our best advice is to use a Steam Jet Cleaner, such as the one Kopykake offers.                     

Use short 1-2 second blasts to clear you clog

This Steam Jet Cleaner will blast most stubborn blockages out of your clogged print head, however, here are a number of methods you can employ:

NOTE: Steam Cleaner is NOT recommended for Epson Printers....as the Printhead in the Epsons are not removable....

1. Make sure all cartridges have ink in them
2. Perform a Deep Clean operation through your printer properties (click on Start, Printers & Faxes, right click on your printer and click on Properties. Choose the maintenance tab and click on deep clean. Choose all colors)
3. Now perform a Nozzle Check from the same maintenance tab
4. From the print out, determine which ink is not coming through. The print should show a table of black (a checkbox of black line), 2 stripes of cyan, 2 of Magenta and 1 of Yellow. Whichever isn't showing a solid line identifies the inkjet that is blocked. If all colors are showing strong solid lines then your problem is fixed. If not, perform another deep clean and another nozzle check. If still no improvement; move on to the next point.
5. Remove the inks and tap them firmly on a piece of white paper towel . You are looking to see if ink comes out of the cartridges or not. If not, then the cartridges could be at fault; but if ink is showing on the paper then we need to turn our attention to the print head.
6. Steam Jet Clean the print head . Remove your inks and print head. Using our Steam Jet Cleaner (preferably over a trash can to catch the mess!) position the Steam Jet Cleaner nozzle over the inkjet heads (the circles that the cartridge sponges sit over) and pull the trigger for 1-2 seconds. Steam will jet through the inkjet clearing out stubborn clogs. Of course, colored steam / hot water will fly out the underneath of the print head so be sure not to get in its way. Repeat this process for all inkjets in the print head. Place your cartridges back into the print head.
7. Kleaning Kartridges. You could also try removing your inks and replace them with our Kleaning Kartridges. Perform a deep clean operation. Then put your edible inks back in the print head and perform a regular cleaning operation.
8. Perform a Nozzle Check. What does the pattern look like now? If it isn't showing strong solid lines of color then we need to try something else. Remove your ink, and remove your print head. Sit the print head in a shallow bowl (1/2") of airbrush cleaning fluid, warm distilled, or deionized water.. Place the tip of a syringe (such as that found in our Syringe Cleaning Kit) over the inkjet heads (the circles that the cartridge sponges sit over) and pull the plunger to suck the cleaning fluid up through the print head. This will clear a clog. Once you've done this, replace the inks and try a Nozzle Check. How is it now?
9. If your Nozzle Check is still not showing solid lines of color then you need to repeat one, or all of the above steps until it does.

If when you tapped the cartridges on the white paper towel color did not come out of them, you need to remove the airlock that is likely to be causing the problem. Sometimes turning the inks upside down will do it (try it then put them in the printer and perform a Nozzle Check to find out).

Sometimes you'll need to pierce a small hole in the middle of the cartridge top (on the sponge side of the tank) with a pin or tack.

Then put them back into the print head and try the Nozzle Check again.

It is entirely possible that the clog is very stubborn and will need numerous deep

cleans / steam jets / Kleaning Kartridge uses to clear.
