Repairs and Adjustments
• If the RADC Measurement is more than 100 bits from the RADC Target for YMC
(more than 80 bits for K), LUT’s cannot compensate, and toning up or down is
required. If one color is out of range, the other colors may display an Up or Down in
the Tone Judge column to move closer to their targets, even though they are within
the appropriate range.
• Machines with ATC Sensors: The RADC targets shown on the dC922 T
RC Contr
ol/
Toner Density Adjustment screen are humidity adjusted ADC targets that correspond
to NVM’s 773-281 thru 773-284. They are not the final TC adjusted ADC targets that
the RADC measurements are being compared to with this configuration. The final
TC adjusted ADC targets can only be found in NVM’s 773-961 thru 773-964. using
these final TC adjusted ADC targets, the same 100 bits for YMC (80 bits for K) tone
up/down criteria as above applies.

ADJ 9.1.7 TRC Adjust (dC924)/TRC Check PG (dC939)
Purpose
To manually fine adjust the low/medium/high densities (TRC) for each color.
NOT TO BE USED AT THIS TIME.
NOTE: Although it appears that the densities can be adjusted independently for different
sc
reen ty
pes, this is not the case. An adjustment for one screen type will affect all of the
screens (300, 150C, 200R, and 600). Also, there is quite a bit of overlap among the low,
medium, and high densities. For these reasons, it is recommended that dC924/939 not be
used.
