Firstly it. must be stated that a heavy-handed person, and one without a proper sense of mechanism is no fit companion for a sick typewriter, the essentials necessary in the repairer are : that he should be light in touch, handy in the use of light tools, careful, have a good sense of mechanism, with some adaptability to be able to make a quick running repair, if a complete new part is not ready to his hand. A really good workman, without having seen the particular type of machine before, can by studying the mechanism discover what is wrong, and make either a running or permanent repair. A machine that has some slight disorder will most probably be found to have some loose part out of adjustment, a good man will quickly find this and put it right, an indifferent worker will be seen to make anything up to half a dozen adjustments at once, apparently in the hope that one of them will put the machine right ; such a workman should be thrown out at once before he wrecks the whole machine.

(1) ;Space Bar Will Not Go Down

Clearly something is preventing the movement, turn the machine over and follow the mechanism through ; the defect should be quite obvious, also the remedy.

(2) ;Space Bar Stays Down

Proceed as above.

(3) ;Spare Bar Works but Paper Carrier does not move

Examine to see whether the spring controlling the movement of the carrier is broken, or the cord between the spring and the carrier, if the latter it is easy to fit a new cord, but if the spring is so broken that not enough is left to carry on with, then if another spring cannot be obtained at once, proceed to rig up a temporary arrangement with either another spring, or a rubber or elastic band, such a temporary spring need not be fixed into the original spring case, in case of need one end could even be fastened etc., on to the desk or table top. If a defective spring is not the real reason, then examine all the mechanism between the two points thoroughly.

(4) ;Main Base Or Frame Of The Machine Broken

These are sometimes made of cast iron, and sometimes are steel pressings, in either case a good repair can quickly be made by fitting a thin steel ptote over the fracture, and holding it firmly to both sides by small bolts, holes for which must be drilled in both halves or pieces of the frame, etc. Care must be taken to see that the frame or base, etc., is quite in correct alignment before bolting up ttnally, otherwise the machine is likely to be twisted, and work indifferently.

(5) ;Impressions Have Got Rapidly Faint

Most likely to be due to the ribbon not being carried across the impression space properly. First see whether it is not due to the ribbon being at one end of its travel ; if so, throw over the reverse lever, if this is not the fault it still must be that the ribbon is stuck in some way, watch and note which way it is pulling : this will show on which side the fault lies, then trace the mechanism through.

(6) ;Impression Very Uneven

Firstly, note whether all letters do the same thing ; if so, then the paper is moving about. Find the reason. If, however, only one or a few letters do it, and most likely it is only those on one type bar, then examine very carefully to see whether that particular type bar is not bent or twisted or both : it almost certainly will be. If so, it must carefully be bent back into place, but if the type bar is not out of place, then it can only be that the type block is loose or shifted on the type bar, see " Fitting Type Blocks," later on, (14) and (15).

(7) ;Two Impressions In One Place

This is caused by the paper carrier not working, see (3) above. Also it might be well to see whether there is enough tension on the spring controlling the paper carrier movement : give some more.

(8) ;Lines Not The Same Distance Apart

This always occurs when the paper carrier is pushed back for a new line and the automatic gear is expected to advance the paper round for a fresh line, but fails to do so. with the result that two lines are written on top of each other. The fault must lie in the mechanism that rotates the paper platen, but. of course, it may be that, either it is not being operated at all, or it is not working properly. Careful scrutiny of the mechanism will show the fault and its remedy.

(9) ;Ribbon Wears Into Holes

Unless very old, this must be due to the ribbon travel being faulty, see (5) above.

(10) ;Warning Bell Does Not Ring

This should be rung by either an attachment on the under side of the paper carrier or mechanism moved by it. Work the carriage to and fro and watch carefully : the trouble and remedy must be obvious.

(11) ;Impressions Not Uniform

Try typing on a single sheet of paper, then again on paper, say 6 thick on the platen, if the latter is good but not the former, then it is most probably due to the surface of the platen or paper roller being very worn, and not presenting an even surface underneath the paper, which is sometimes supported underneath, and sometimes not supported. Of course, a new rubber roller will put things right, but a very good quick repair can be made by getting some coarse, also fine glass paper, together with a smooth piece of wood, taking the carriage off the machine if possible.
