How to scan - scan mode.

Please notice that CC Capture is measuring four times on each patch - two times for each patch in each row, and scan each row twice offsetting a little for the second scan. The following picture shows where to start and end instrument movement.

Exact2 users should see the start point through the internal camera:

Never start from the center of the first patch, but from the edge.

Spot mode

Please try to find four different samples on each patch according to schema:

Important information for the eXact users before using eXact with T-42

• eXact can measure T42 in a spot mode or, when equipped with the scan adapter, also in a scan mode.
• We recommend ensuring the scan adapter is touching the printout only with rubber rollers while moving over it. Surface unevenness will cause abrasions on the T42 target (ruining it).
• To test if only rubber rollers are touching target, put a thin sheet of paper on target, then roll unit as if scanning, if instrument easily rolls and paper does not interfere, then you are good.  
• Also, please check the cleanliness of the rollers, including the fifth wheel with a zebra wheel. When eXact is used to measure wet prints,  the rollers often get dirty with ink. This can then transfer to the new print that you are measuring. Cleanliness can be checked by making circular movements of the trolley on a clean sheet of paper. If we see ink on the paper, it means that the rollers are dirty and they should be carefully cleaned.
• When measuring T-42, don't try to slide the instrument fast. Slower speed helps to get more accurate data.
• Be sure that your eXact has the latest firmware version. Use eXact Manager to check/upgrade it. Some older models may require upgrading at the factory! Check if your eXact has an "M1 Part 2 Export" function.
• Due to an internal instrument library bug, all Mac users have to disable simultaneous multi-M-condition measurements — disabled: "M1 Part 2 Export". We are waiting for the fix.

When using T-42 with eXact for the first time.

1. Register your T-42 serial number in Instrument Inspector (one registration is for all instruments). Each target has a unique serial number, e.g., T42-00001.
2. Create a baseline - that will represent how the instrument. Perform a few scans before stabilizing the measurement conditions. CC Capture will detect a missing baseline and will guide the operator through the creation procedure.
3. When the baseline is created and results are satisfactory (comparable to our example) repeat measurement one more time to see verification on the timeline.

Periodical Instrument Verification 

Perform verification of your instrument. Take care to keep your instrument and target clean. If you have more than one target be sure to select the proper serial number!
