I had this weird error code and when I contacted sharp tech support they suggested a full pm, I mean they wanted me to change everything . Error was " DATA_SUB_K_F_1ST 10 " when doing SIM 50-22. I had a co-worker go with me to give the MFP a second look. We found the secondary transfer roller slighty out of place causing the error. Just wanted to put this here for any one googling DATA_SUB_K_1ST 10.
Also bonus here's what they told me:
Description: MFP displays "DATA_SUB_M_F_HEAD 30" error when SIM 50-22 (Image Registration Adjustment) is used to adjust Image Registration.
Call Notes: 1-Set SIM 50-10 (Used to adjust the black print image magnification ratio and the off-center position) Value A BK MAG to default. 2-Set SIM 50-20 (Image Registration Adjustment) Items A~I to default, and select OK button. 3-Move to SIM 50-22 (Image Registration) and execute. 4-Clean and calibrate Image-Density Sensors, execute SIM 44-2 (Image-Density Sensor Sensitivity). 5-Perform manual Laser Skew Adjustment 4B as shown in the service manual. Check LSU. 6-Confirm error does not return and perform phase adjustments as needed. 7-Confirm copy quality is acceptable(PM machine). 8-Check or replace Main Drive unit. ]Based on the information provided during the time of the call, the hotline Agent assisting during the call may have suggested part(s) replacement. Decision to replace part(s) is ultimately at the dealer’s discretion. Sharp’s National Parts Center does not honor requests for parts returns that are the result of “Hotline Suggestions”. Hotline suggestions are not parts warranty authorization, and in no way supersedes good troubleshooting and good service procedures.
