E061The start of our investigation was brought to our attention by Mr Guy Pinnockresident engineer at Santander in MK experiencing numerous E061 errors .What was discovered is that around the 350/400k copy/print amount the feed actuators have become worn, Part nos 6LH56305000 ACTR-RGST-L-47X6LH56304000 ACTR-RGST-U-47X

After replacement the device showed a improved level of reliability and the E061 error code was eliminated .

E130 & Skewing This error code was brought to our attention by Mr Darren Stocks at Arena group Leeds experiencing numerous errors including E130 & Skewing footprints 12615 .What was discovered is that around the 400/420k copy/print amount the feed actuators have become worn, also various feed guides within the feed system had become severely worn causing feed jams of varying types and skewing Items replaced Espos page 18 item 1 6LH56121000 GUIDE-FEEDER-L-470 (modified)Espos page 18 item 4 6LH56104000 ACT-FEED-470Espos page 18 item 2 6LH56101000 GUIDE-OP-UEspos page 18 item 26 6LH56119000 HOLDER-ROL-FEEDER (modified)Espos page 21 item 7 6LH56300000 GUIDE-RGST-L-470Espos page 21 item 10 6LH56304000 ACTR-RGST-U-47XEspos page 21 item 12 6LH56305000 ACTR-RGST-L-47XEspos page 20 item 14 6LH51433000 HOLDER-SPGEspos page 20 item 11 6LH51206000 GUIDE-RGST-UPEspos KD-1026 page 1 item 18 6LE99167000 GUIDE-FEED-UAfter replacement the device showed a improved level of reliability and the E130 error code and skewing was eliminated .

After the visit to Schulmans it was decided that we should look at several different locations and using various paper types and device volume loading.It was discovered numerous levels of wear on the items mentioned and this could have the potential to create situations of customer dissatisfaction as sometimes the error codes generated do not always relate to the root cause with engineers changing drive clutches etc.. Having a financial impact on dealer and direct operations but also in the device availability to the end user causing machine uptime to be lost .So we would like engineering awareness levels need to be raised to compensate for these phenomenon's with the possibility of TTEC further investigating the materials used in manufacture to create more durable items .Thank you to the contributors to the study George Phillips TDS , Guy Pinnock ,Ian Davies (Direct) & Darren Stocks (Arena Group)
