How do I prepare my Epson Stylus Pro 4900 / 7900 / 9900 for GMG ColorProof? – GMG Support

Only an optimally set up printer will produce optimal proofs. In the following section, you will learn how to prepare your printer before using it for the first time with GMG ColorProof to ensure the best results every time.

The optimal procedure for setting up your printer depends on whether it is a brand new device or one that has been used before.

How to set up a brand new printer for GMG ColorProof:

The setup includes a printer-specific part and a media-specific part. Please always start with the device-specific settings.

The printer-specific part:

Print a nozzle test to make sure that there are no blockages inside the printing nozzles.
In case of blocked ink nozzles, perform 1 - 2 power cleanings for the affected colors.
Perform a print head alignment. Please note the sequence here: first align for unidirectional printing, only then for bidirectional printing.

You can find detailed instructions on the listed steps in the maintenance section of the Epson user manual, which you can download from the manufacturer's website.

The media-specific part:

Insert the correct GMG media. Make sure that the roll is as full as possible.
Perform a paper feed adjustment.
If your printer has an internal measurement device of type ILS30, we recommend our automatic paper feed correction. If your printer does not have an integrated measuring device of type ILS30, you can alternatively perform a manual feed correction.

Please perform these two steps each time you use a new medium.

Put the measuring unit back in place.
