Frequently the bristles of the brush will get caught in the partitions of the magazine and pull out of the brush. These can usually be removed by dragging the edge of a soft pine yard-stick across them.
Keep the various parts of the machine, with which the matrices come in contact, clean and free from oil, and the magazine will not get dirty for some time.
CLEANING MATRICES
Matrices to be cleaned should be placed on a flat galley. With an ink eraser (Banner Eberhard Faber No. 1071) remove the gum or dirt from the lugs and the face. Then blow the loose dust off with the air. Place another galley bottom side up over the galley of matrices and turn both galleys and the matrices over. The back lugs and back side of the matrices may then be cleaned the same as the face.
Magazine Hints
Never oil the escapements nor put oil in the magazine. To do so will cause escapement trouble.
Do not slam the magazine entrance when closing it. There may be a matrix overhanging the edge that you have overlooked, and you will damage the matrix and the back end of the magazine.
Never pound the magazine to make matrices drop. Locate the cause of the trouble and remove it.
Don’t forget, when pulling down the magazine entrance, to do so quickly, as opening it slowly is liable to cause a matrix to fall into the magazine flatwise.
Never try to force a matrix past the escapement. If it will not come through easily, pull it out the back way.
