1 P.F.E. INTERNATIONAL TO : ALL UK ENGINEERS AND OVERSEAS AGENTS TECHNICAL BULLETIN N /102 Please ensure this Technical Bulletin is read by all technical staff involved in the maintenance and repair of P.F.E machines. This bulletin must be read by all P.F.E. engineers involved in the maintenance and service of Maximailer/Automailer 4, and must be attached to all copies of the Maximailer/Automailer 4 Service Manual. MAXIMAILER VARIOUS OPTIONS This Technical Bulletins covers a number of options available to enhance functionality for specific needs. 1. Operator-settable separator (3 Plate Folder) 2. Mods for glossy material (3 Plate Folder) 3. Anti-static Brushes (3 Plate Folder Accumulator) 4. Alternative feed tyres and parts (Feeder, Head & 3 Plate Folder) 5. Technical Tips document Description and fitting of these options is shown below. 1. Operator-settable separator The standard separator on the 3 plate folder is spring-loaded and operates with a preset gap for 80gsm (20lbs bond) paper. Under certain circumstances (eg. extra thick material) it may be necessary to open the gap, or in some cases to close it. As standard, this is an engineer operation (described in section in the Service Manual), but with some stationery, this may not provide a sufficiently sensitive adjustment. The operator-settable separator allows the operator to set the gap using a knurled knob after opening the side cover of the 3 plate folder. It can be specially useful when double feeding has been a problem with the standard separator, as it allows 'fine tuning'. The retrofit includes a special internal (black) cover to provide access to the knurled knob. Retrofit Kit To obtain the retrofit kit, order part no. A3263A (3-tray machines) or A3264A (1-tray machines). This consists of the following parts.quantities shown in brackets are for 1-tray machines Part No. Description Qty.

If not already supplied as a single assembly, assemble the separator bracket assembly as shown in section 4c-40 in the Service Manual. 2. Open the side cover on the LH side of the machine and remove the side cover on the RH side. Also remove the black internal cover on the LH side. This reveals the separators, as shown in Fig. 1 below. There is one separator for each tray fitted. Spring Pivot arm Bracket assembly Fig Remove and discard the spring, and also the spring on the RH side, then remove the 2 screws securing the pivot plate to the separator beam. Take off the plate and discard it. Remove the bracket assembly below the plate and discard it. 4. Fit the new bracket assembly using existing screws, then the new pivot plate, also using existing screws, as shown in Fig. 2 below. Fig. 2 Page 2 of 5

Attach the cover using existing screws. 7. Set the separator gap to suit 80gsm (20lbs bond) paper, or to a different setting as required. This is most easily achieved by removing the top tray, and for 3-tray machines, the second tray also. Lift out the infeed bridge (with cork strips) to prevent drag from the pre-feeder. Slide a sheet of the stationery into the separator gap and adjust the knurled knob until a moderate drag is felt on the paper as it is withdrawn rearwards. Refit the infeed plate and trays. 8. Refit the side cover and test run the machine. Make further separator adjustments if required. 2. Mods for glossy material If glossy material is being used, feeding may be improved by the fitting of an alternative infeed guide B0173A and a stronger platform spring G1215A on the top hopper. Infeed guide This is attached to the infeed bridge which can be lifted out after removing the hopper, as shown in Fig. 3 below. The new item is slightly shorter, exposing more of the cork strips, and helps better preseparation if double feeding is a problem. Infeed guide B0173A Platform spring Fig. 3 The stonger spring holds the paper stack more firmly against the pre-feed roller and has been found to be more effective with glossy material. To fit the spring, remove the pivot at each corner of the hopper tray and lift it out. 3. Fitting anti-static brush to accumulator If static is a particular problem, anti-static brushes can be fitted to the accumulator. These are attached to the collate gate paper guide which is located inside the 3 plate folder chassis, at the lower end of the accumulator tray (see Fig. 4 on the following page). Parts required will be: Collate gate paper guide R2701A Qty. 1 Anti-static brush B0014A Qty. 2 M4 Nyloc nut E3505A Qty. 4 Page 3 of 5

4 Anti-static brush B0014A Collate gate paper guide R2701A M4 Nyloc nut E3505A Extrusion shown for reference only Fig. 4 Note that collate gate paper guide R2701A is fitted with M4 studs for attaching the brushes - plates without brushes are R2352A. To retrofit the brushes, the overguide must be removed - proceed as follows: 1. Open the LH side cover of the 3 plate folder and remove the black inner cover. Also remove the RH side cover (section in the Service Manual). 2. On the RH side, remove gears as shown in Fig. 5 below. Remove the 'E' clip and flanged bearing on the overguide shaft. Also remove the 'E' clip, waved washer and flanged bearing on the LH side. Lift the overguide out of the machine. Overguide shaft - remove gear and drive pin for access to 'E' clip Remove idle post and gear Fig. 5 Screws for collate gate paper guide 3. Remove the 2 screws each side securing the collate gate paper guide and fit the new item after attaching the anti-static brushes. 4. Refit the overguide, gears and side covers. (Remember the drive pin for the gear on the RH side). Page 4 of 5

5 4. Feed Problems Note: This section will also be shown in the Service Manual for a more permanent record. Below are details of non-standard tyres and parts that may help to solve some feed problems. Note that some separation problems with glossy or semi-glossy paper may be due to the separator tyres, pads and transport wheels becoming coated with paper glazing agent. When this occurs the solution is to ensure frequent cleaning of these items. Part Number Roller/ Separator Tyre Application Qty. Description D0052A Jog Tyre 2 off (fitted to outer wheels) These tyres are standard on the envelope feed and are used to provide improved grip and drive. C8194A Slotted Feed Tyre 6 off This feed wheel has advantages when feeding inserts with a powdery finish. D0037A Feed Tyre C8193A Roller Hi - Grip EPDM A7174A Special Ins Separator Assembly This version exposes more of the friction pad to the insert pack and can help with forms that are proving difficult to separate. B0173A Infeed Guide 3 Plate Folder per hopper Alternative infeed guide exposes more cork to assist pre-separation of glossy stationery. G1215A Spring 3 Plate Folder (top hopper) Alternative Platform Spring (Stronger) that improves feeding separation of glossy stationery. B7803A Overguide An over-guide is available to overcome feed problems associated with peeling open of folded documents on pick-up. This is a guide similar to the one used to keep the envelope flap closed on the envelope feeder. D0058A Slotted Feed Wheel D0059A Coated Feed Wheel A7217A (B1864S cover) Pre-feed Assembly Feeder This assembly can be fitted to improve the pickup of propeller cut envelopes.note. B1864S cover must be fitted with this assembly. 5.
